[SCSI] lpfc 8.3.16: FCoE Discovery and Failover Fixes
- Add support for re-reg'ing changed VPI w/o unregister VPI
- Copy WWN and state from old nodelist when target DID change.
- Clean up old nodelist rport and put the nodelist when target DID change.
- Clear the VFI_REGISTERED flag when UNREG_VFI completes.
- Made both checks of port_state against LPFC_FLOGI and LPFC_FDISC
non-inclusive for ignoring CVL events.
- Added logic to stop retrying of the ongoing PLOGI and FDISC if
transitioned back to the FCF rediscovery state in reaction to CVL.
- Removed the dependency of scanning of all the available FCF table
entries for bulding round-robin bitmap.
- Use the lpfc_sli4_fcf_rr_read_fcf_rec() in responding to
individual New FCF found event.
