[SCSI] zfcp: Changed D_ID left port disabled

Browse source 
If the destination ID (D_ID) of a remote storage port changed, e.g.
re-plugged cable on the switch in a different switch port, the port
was never (re-)attached within Linux. This patch fixes the broken
mapping between the WWPN and the D_ID.
