[SCSI] lpfc 8.3.3 : Fix various SLI-3 vs SLI-4 differences

Browse Source 
Contains the following changes
- Set the CT field of FDISC to 3
- Fixed over allocation of SCSI buffers on SLI4
- Removed unused jump table entries
- Increase LPFC_WQE_DEF_COUNT to 256
- Updated FDISC context to VPI
- Fixed immediate SCSI command for LUN reset translation to WQE
- Extended mailbox handling to allow MBX_POLL commands in between async
  MBQ commands
- Fixed SID used for FDISC
- Fix crash when accessing ctlregs from sysfs for SLI4 HBAs
- Fix SLI4 firmware version not being saved or displayed correctly
- Expand CQID field in WQE structure to 16 bits
- Fix post header template mailbox command timing out
- Removed FCoE PCI device ID 0x0705
