Subject: [PATCH 3.10 108/129] libceph: create_singlethread_workqueue() doesnt return ERR_PTRs

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@...cle.com>

commit dbcae088fa660086bde6e10d63bb3c9264832d85 upstream.

create_singlethread_workqueue() returns NULL on error, and it doesn't
return ERR_PTRs.

I tweaked the error handling a little to be consistent with earlier in
the function.
