9p: add remove function to trans_virtio
Request from rusty: Just cleaning up patches for 2.6.25 merge, and noticed that net/9p/trans_virtio.c doesn't have a remove function. This will crash when removing the module (console doesn't have one because it can't really be removed). Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
