[v2.6.34-stable 190/213] udf: fix retun value on error path in udf_load_logicalvol

From: Paul Gortmaker
Date: Wed Feb 05 2014 - 15:16:52 EST

-------------------
This is a commit scheduled for the next v2.6.34 longterm release.
http://git.kernel.org/?p=linux/kernel/git/paulg/longterm-queue-2.6.34.git
If you see a problem with using this for longterm, please comment.
-------------------

commit 68766a2edcd5cd744262a70a2f67a320ac944760 upstream.

In case we detect a problem and bail out, we fail to set "ret" to a
nonzero value, and udf_load_logicalvol will mistakenly report success.
