scsi: scsi_transport_srp: Don't block target in SRP_PORT_LOST state
rport_dev_loss_timedout() sets the rport state to SRP_PORT_LOST and the
SCSI target state to SDEV_TRANSPORT_OFFLINE. If this races with
srp_reconnect_work(), a warning is printed:
Mar 27 18:48:07 ictm1604s01h4 kernel: dev_loss_tmo expired for SRP port-18:1 / host18.
Mar 27 18:48:07 ictm1604s01h4 kernel: ------------[ cut here ]------------

Avoid this by not trying to block targets for rports in SRP_PORT_LOST
state.
