[SCSI] zfcp: fix: problem in send_els_handler when D_ID assignment changes
From: Maxim Shchetynin <maxim@de.ibm.com>
Fixes a bug in zfcp_send_els_handler. If D_ID assignments for ports
are changing between initiation of one ELS request and its completion
the wrong port might be accessed in the completion for that ELS
request. Thus a pointer to the port has to be passed for ELS requests
to identify the port structure if required.
