vduse: do not take rwsem at reset work flush
Next patches need to check suspend flag at this work item, and the
rwlock is used to protect the suspend flag update. If the work takes
the rwlock too it will produce a deadlock.
Make flushing work do nothing when called by de-initializing everything:
vq->ready, vq->kickfd, vq->cb.callback.
