vhost_scsi: Handle vhost_vq_work_queue failures for TMFs
vhost_vq_work_queue will never fail when queueing the TMF's response
handling because a guest can only send us TMFs when the device is fully
setup so there is always a worker at that time. In the next patches we
will modify the worker code so it handles SIGKILL by exiting before
outstanding commands/TMFs have sent their responses. In that case
vhost_vq_work_queue can fail when we try to send a response.
This has us just free the TMF's resources since at this time the guest
won't be able to get a response even if we could send it.
