[SCSI] zfcp: resolve false usage of dd_data in fc_rport
The fc_rport structure reserves a reference where a LLD can put information required in a situation where the fc transport class is triggering LLD callbacks. The zfcp driver was using this variable directly which is discouraged. This patch solves this issue by making this reference unnecessary. In addition the dev_loss_tmo callback is removed, it is not required: zfcp does not access the fc_rport after calling fc_remote_port_delete.
