If there is no corresponding scsi_device for a LUN,
tcm_loop_port_unlink() complains that it "Unable to locate struct
scsi_device for " the device and keep %tl_tpg_port_count as is. However,
such situation is legal when we delete a SCSI device using
/sys/class/scsi_device/${lun}/device/delete. We can safely ignore the
missing SCSI device case here.
