Annex A12 of the IBTA spec defines additional information that needs
to be provided through the CM exchange relating to usage of ZBVA (Zero
Based VAs) and Send With Invalidate over an iSER connection.

Currently, the initiator sets both to not supported, but does provide
the header so that existing iSER targets can be patched to start
looking on the private data carried by the CM.

This is a preparation step to enable iSER with HW drivers for which
FMRs are not supported, such as mlx4 VF instances or new HW devices
which might support only FRWR (Fast Registration Work-Requests) along
the details of the IB_DEVICE_MEM_MGT_EXTENSIONS device capability.

Commit 819a087316a6 ("IB/iser: Avoid error prints on EAGAIN
registration failures") not only eliminated the error print on that
case, but rather also modified the code such that it doesn't return
any error to upper layers.  As a result a wrong mapping was used.  Fix
this to correctly return the error in that case.

Pull SCSI target update from Nicholas Bellinger:
 "The highlights this round include:

   - Add fileio support for WRITE_SAME w/ UNMAP=1 discard (asias)
   - Add fileio support for UNMAP discard (asias)
   - Add tcm_vhost hotplug support to work with upstream QEMU
     vhost-scsi-pci code (asias + mst)
   - Check for aborted sequence in tcm_fc response path (mdr)
   - Add initial iscsit_transport support into iscsi-target code (nab)
   - Refactor iscsi-target RX PDU logic + export request PDU handling
     (nab)
   - Refactor iscsi-target TX queue logic + export response PDU creation
     (nab)
   - Add new iSCSI Extentions for RDMA (ISER) target driver (Or + nab)

  The biggest changes revolve around iscsi-target refactoring in order
  to support the iser-target driver.  This includes the conversion of
  the iscsi-target data-path to use modern se_cmd->cmd_kref counting,
  and allowing transport independent aspects of RX/TX PDU
  request/response handling be shared across existing traditional
  iscsi-target code, and the new iser-target code.

  Thanks to Or Gerlitz + Mellanox for supporting the iser-target
  development effort!"

Pull SCSI target update from Nicholas Bellinger:
 "The highlights this round include:

   - Add fileio support for WRITE_SAME w/ UNMAP=1 discard (asias)
   - Add fileio support for UNMAP discard (asias)
   - Add tcm_vhost hotplug support to work with upstream QEMU
     vhost-scsi-pci code (asias + mst)
   - Check for aborted sequence in tcm_fc response path (mdr)
   - Add initial iscsit_transport support into iscsi-target code (nab)
   - Refactor iscsi-target RX PDU logic + export request PDU handling
     (nab)
   - Refactor iscsi-target TX queue logic + export response PDU creation
     (nab)
   - Add new iSCSI Extentions for RDMA (ISER) target driver (Or + nab)

  The biggest changes revolve around iscsi-target refactoring in order
  to support the iser-target driver.  This includes the conversion of
  the iscsi-target data-path to use modern se_cmd->cmd_kref counting,
  and allowing transport independent aspects of RX/TX PDU
  request/response handling be shared across existing traditional
  iscsi-target code, and the new iser-target code.
