[SCSI] libfc: register FC4 features with the FC switch

Browse source 
Customers and certification tests have pointed out that we don't
show up on the switch management software as an initiator.

On some MDS switches 'show fcns database' command shows libfc
initiators as 'fcp' not 'fcp:init' like other initiators.

On others switches, I think the switch gets the features by doing a PRLI,
but it may be only certain models or under certain configurations.

Fix this by registering our FC4 features with the RFF_ID CT request
after local port login and after the RFT_ID.
