9p/trans_virtio: fix hot-unplug

On device hot-unplug, 9p/virtio currently will kfree channel while
it might still be in use.

Of course, it might stay used forever, so it's an extremely ugly hack,
but it seems better than use-after-free that we have now.

[ Unused variable removed, whitespace cleanup, msg single-lined --RR ]
