FC protocol fixes.
 - Fix send sequence logic to handle multi SGL IOCBs.
 - Fix FDISC completion always setting VPORT state to failed.
 - Ported the fix on reporting of max_vpi to uppper layer.
 - Fix incorrect number of Vports allowed to be created.
 - Fixed Dead FCoE port after creating vports.
 - Added handling of ELS request for Reinstate Recovery Qualifier (RRQ)
 - Handle unsolicited CT exchange initiator receiving CT exchange ABTS
 - Migrate LUN queue depth ramp up code to scsi mid-layer.
 - Made ABTS WQE go to the same WQ as the WQE to be aborted.
 - Fix Vport does not rediscover after FCF goes away.
 - Fixed lpfc_unreg_vfi failure after devloss timeout.
 - Fixed RPI bit leak.
 - Fix hbq pointer corruption during target discovery.
