Anirudh Rayabharam d55df42ef3 rapidio: handle create_workqueue() failure 
commit 69ce3ae36d upstream.

In case create_workqueue() fails, release all resources and return -ENOMEM
to caller to avoid potential NULL pointer deref later. Move up the
create_workequeue() call to return early and avoid unwinding the call to
riocm_rx_fill().
