virtio_blk: fix race at module removal If a device appears while module is being removed, driver will get a callback after we've given up on the major number. In theory this means this major number can get reused by something else, resulting in a conflict. To fix, cleanup in reverse order of initialization. Signed-off-by: Michael S.
