[SCSI] lpfc 8.3.16: SLI Additions, updates, and code cleanup

- Remove unneeded Endian swap for Block Guard IOCB response
- Add a check for mailbox active before issuing the heartbeat command
- Correct heartbeat last_completion updates to avoid unneeded heartbeats
- Add Security crypto support to CONFIG_PORT mailbox command
- Add fips level and fips spec revision sysfs parameters
- Remove duplicate setting of ext_byte_len fields in lpfc_bsg_issue_mbox
- Switch call to memcpy_toio to __write32_copy to prevent unaligned 64 bit copy
- Change log message 0318 from an error to a warning as it is not an error
- Patch an incorrect call to lpfc_drain_txq on SLI-3 functions
