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.

Martin, James, we have a small zfcp bugfix.
Would be nice if it could still make it into v5.14-rc1 merge window,
but I'm probably too late for that. v5.14-rc2 is fine, too.
Applies to 5.14/scsi-staging or 5.14/scsi-queue or James' misc branch,
or to the corresponding fixes branch(es).
