[SCSI] zfcp: Update FC pass-through support
Don't access the block layer request, get the payload length instead
from the FC job. Simplify access to the zfcp_port, only the d_id is
required, if the port is no longer accessed later. This is possible
when the els_handler does not access the port pointer from the ELS
request.
