vmbus_sendpacket_mpb_desc() is currently used only by the storvsc driver
and is hardcoded to create a single GPA range. To allow it to also be
used by the netvsc driver to create multiple GPA ranges, no longer
hardcode as having a single GPA range. Allow the calling driver to
specify the rangecount in the supplied descriptor.

Update the storvsc driver to reflect this new approach.

The REPORT ZONES buffer size is currently limited by the HBA's maximum
segment count to ensure the buffer can be mapped. However, the block
layer further limits the number of iovec entries to 1024 when allocating
a bio.

To avoid allocation of buffers too large to be mapped, further restrict
the maximum buffer size to BIO_MAX_INLINE_VECS.

Replace the UIO_MAXIOV symbolic name with the more contextually
appropriate BIO_MAX_INLINE_VECS.

 - Fix the incorrect return type of ata_mselect_control_ata_feature()

 - Several fixes for the control of the Command Duration Limits feature
   to avoid unnecessary enable and disable actions. Avoiding the
   unnecessary enable action also avoids unwanted resets of the CDL
   statistics log page as that is implied for any enable action.

 - Fix the translation for sensing the control mode page to correctly
   return the last enable or disable action performed, as defined in
   SAT-6. This correct mode sense information is used to fix the
   behavior of the scsi layer to avoid unnecessary mode select command
   issuing.

<content type='text'>
With ATA devices supporting the CDL feature, using CDL requires that the
feature be enabled with a SET FEATURES command. This command is issued
as the translated command for the MODE SELECT command issued by
scsi_cdl_enable() when the user enables CDL through the device
cdl_enable sysfs attribute.

However, the implementation of scsi_cdl_enable() always issues a MODE
SELECT command for ATA devices when the enable argument is true, even if
CDL is already enabled on the device. While this does not cause any
issue with using CDL descriptors with read/write commands (the CDL
feature will be enabled on the drive), issuing the MODE SELECT command
even when the device CDL feature is already enabled will cause a reset
of the ATA device CDL statistics log page (as defined in ACS, any CDL
enable action must reset the device statistics).

Avoid this needless actions (and the implied statistics log page reset)
by modifying scsi_cdl_enable() to issue the MODE SELECT command to
enable CDL if and only if CDL is not reported as already enabled on the
device.

And while at it, simplify the initialization of the is_ata boolean
variable and move the declaration of the scsi mode data and sense header
variables to within the scope of ATA device handling.

Commands that have not been completed with scsi_done() do not clear the
SCMD_INITIALIZED flag and therefore will not be properly reinitialized.
Thus, the next time the scsi_cmnd structure is used, the command may
fail in scsi_cmd_runtime_exceeded() due to the old jiffies_at_alloc
value:
