independent of VFI.
- Add code to unregister, re-init and re-register physical port VPI

- 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.
