[SCSI] lpfc 8.3.14: SCSI and SLI API fixes

- Fixed accounting of allocated SCSI buffers when post sgl fails.
- Restrict scsi buffer allocation based on LUN count (sdev_cnt).
- Create __lpfc_sli_free_rpi that doesn't take out the hbalock.
- Modify lpfc_sli_free_rpi to call __lpfc_sli_free_rpi.
- Call __lpfc_sli_free_rpi in lpfc_cleanup_pending_mbox.
- Do not swap the strings returned in mailbox commands and do
  not swap byte aligned data in VPD.
