On a randconfig build without CONFIG_SCSI_LPFC_DEBUG_FS, I ran into
multiple compile failures:

drivers/scsi/lpfc/lpfc_debugfs.h: In function 'lpfc_debug_dump_wq':
drivers/scsi/lpfc/lpfc_debugfs.h:405:15: error: 'DUMP_FCP' undeclared (first use in this function); did you mean 'DUMP_VAR'?
drivers/scsi/lpfc/lpfc_debugfs.h:405:15: note: each undeclared identifier is reported only once for each function it appears in
drivers/scsi/lpfc/lpfc_debugfs.h:408:22: error: 'DUMP_NVME' undeclared (first use in this function); did you mean 'DUMP_NONE'?
drivers/scsi/lpfc/lpfc_nvmet.c: In function 'lpfc_nvmet_xmt_ls_rsp_cmp':
drivers/scsi/lpfc/lpfc_nvmet.c:109:2: error: implicit declaration of function 'lpfc_nvmeio_data'; did you mean 'lpfc_mem_free'? [-Werror=implicit-function-declaration]
drivers/scsi/lpfc/lpfc_nvmet.c: In function 'lpfc_nvmet_xmt_fcp_op':
drivers/scsi/lpfc/lpfc_nvmet.c:523:10: error: unused variable 'id' [-Werror=unused-variable]

They are all trivial to fix, so I'm doing it in a combined patch here.

lpfc cannot establish connection with targets that send PRLI in P2P
configurations.

If lpfc rejects a PRLI that is sent from a target the target will not
resend and will reject the PRLI send from the initiator.

Reviewing the result of what was just added for Kconfig, we made a poor
choice. It worked well for full kernel builds, but not so much for how
it would be deployed on a distro.

Here's the final result:
- lpfc will compile in NVME initiator and/or NVME target support based
  on whether the kernel has the corresponding subsystem support.
  Kconfig is not used to drive this specifically for lpfc.
- There is a module parameter, lpfc_enable_fc4_type, that indicates
  whether the ports will do FCP-only or FCP & NVME (NVME-only not yet
  possible due to dependency on fc transport). As FCP & NVME divvys up
  exchange resources, and given NVME will not be often initially, the
  default is changed to FCP only.

We see lpfc devices regularly fail during kexec. Fix this by adding a
shutdown method which mirrors the remove method.

This patch addresses the smatch issues identified by Dan Carpenter
in http://www.spinics.net/lists/linux-scsi/msg105665.html

The issues are:

error: we previously assumed 'ndlp' could be null (see line 928)
