Anirudh Rayabharam 1ba7a534a9 rapidio: handle create_workqueue() failure
commit 69ce3ae36dcb03cdf416b0862a45369ddbf50fdf 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().
