[SCSI] zfcp: fix deadlock caused by shared work queue tasks
Each adapter reopen trigger automatically a scan_port task which is waiting for the ERP to be finished before further processing. Since the initial device setup enqueues adapter, port and LUN which are individual ERP actions, this process would start after everything is done. Unfortunately the port_reopen requires another scheduled work to be finished which is queued after the automatic scan_port -> deadlock ! This fix creates an own work queue for ERP based nameserver requests.
