[SCSI] lpfc 8.3.23: Miscellaneous fixes

Miscellaneous fixes

- Do not limit RPI Count to a minimum of 64
- Fix FCFI incorrect on received unsolicited frames.
- Save the FCFI returned in the REG_FCFI mailbox command if it was successful.
- Fixed Vports not sending FDISC after lips.
- Align based on the SLI4_PAGE_SIZE.
- Fixed double byte swap on received RRQ.
- Fixed mask size for the wq_id mask from 0x7F to 0x7FFF.
- Clear FC_FABRIC flag when NPIV LOGO completes (and add a log message).
- Modified driver to skip round robin only when ulpStatus==LOCAL_REJECT
  and word4=SEQUENCE_TIMEOUT to prevent FLOGI to disconnected FCF.
- Don't add rport if driver unloading
