[SCSI] zfcp: Use forced_reopen in terminate_rport_io callback
When running in non-NPIV mode, the port_reopen in terminate_rport_io
might succeed even though the remote port is not available. If the
same port connection is held open from another operating system, the
reopen is only a virtual operation and might not hit the SAN. Fix this
by changing the call to forced_reopen that forces a logout/login
operation in the SAN.
