[SCSI] lpfc 8.3.8: BugFixes: Discovery relates changes

Discovery relates changes:
- Separated VPI_REGISTERED state of physical port into VFI_REGISTERED and
  VPI_REGISTERED state so that driver can unregister physical port VPI
  independent of VFI.
- Add code to unregister, re-init and re-register physical port VPI
  when physical port NportID change.
- Add code to unregister and re-register VPI of a vport when its Nport
  ID change.
- Add code in FDISC completion path to re-start FLOGI discovery when
  a FDISC complete with LOGIN_REQUIRED reason code.
- Fix a memory leak in lpfc_init_vpi_cmpl
- Add code to start a timer for vport to retry FDISC when CVL is received
  by a vport or physical port. If all Nports receive CVLs, then all timers
  are cancelled and a logical link level discovery will be started after
  one second.
- Flush ELS commands after killing all delayed ELS commands.
