vhost-user-fs: do delete virtio_queues in unrealize
Similar to other virtio device(https://patchwork.kernel.org/patch/11399237/), virtio queues forgot to delete in unrealize, and aslo error path in realize, this patch fix these memleaks, the leak stack is as follow:
Direct leak of 57344 byte(s) in 1 object(s) allocated from:
