[SCSI] lpfc 8.3.29: SLI related fixes

SLI related fixes:

- Fix REG_RPI fails on SLI4 HBA putting NPort into NPR state (126230)
- Fix ELS FDISC failing with local reject / invalid RPI. (126350)
- Fix reset port when reset is needed during fw_dump (125807)
- Fix unbounded firmware revision string from port cause panic (126560)
- Fix driver behavior when receiving an ADISC (126654)
- Fix driver not returning when bad ndlp found in abts error event
  handling (126209)
- Add more driver logs in area of SLI4 port error attention and reset
  recovery (126813, 124466)
- Fix failure in handling large CQ/EQ identifiers in an IOV
  environment (126856)
- Fix for driver using duplicate RPIs after lancer port reset (126723)
- Clear vport->fc_myDID in lpfc_els_issue_fdisc to guarentee a
  zero SID (126779, 126897)
- Fix for SLI4 Port delivery for BLS ABORT ACC (126289)
