[SCSI] lpfc 8.3.13: FC Discovery Fixes and enhancements.

Browse Source 
- Retry PLOGI up to 48 times when LS_RJT reason is
  "Unable to supply requested data."
- When dev loss timeout occures do not change state if there
  is an outstanding REG_LOGIN.
- Add logic to ignore REG_LOGIN completion if discovery is
  restarted while waiting for REG_LOGIN.
- Only change state on REG_LOGIN completion if still in
  state waiting for REG_LOGIN completion.
- Only send ADISCs to FCP-2 Targets (not Initiators).
