From: Steffen Maier <maier@xxxxxxxxxxxxx> commit 8b3bdd99c092bbaeaa7d9eecb1a3e5dc9112002b upstream. On remote cable pull, a zfcp_port keeps its status and only gets ZFCP_STATUS_PORT_LINK_TEST added. Only after an ADISC timeout, we would actually start port recovery and remove ZFCP_STATUS_COMMON_UNBLOCKED which zfcp_sysfs_port_fc_security_show() detected and reported as "unknown" instead of the old and possibly stale zfcp_port->connection_info. Add check for ZFCP_STATUS_PORT_LINK_TEST for timely "unknown" report.
