Julian Sun a533603572 gfs2: fix double destroy_workqueue error
commit 6cb9df81a2c462b89d2f9611009ab43ae8717841 upstream.

When gfs2_fill_super() fails, destroy_workqueue() is called within
gfs2_gl_hash_clear(), and the subsequent code path calls
destroy_workqueue() on the same work queue again.

This issue can be fixed by setting the work queue pointer to NULL after
the first destroy_workqueue() call and checking for a NULL pointer
before attempting to destroy the work queue again.
