3.5.7u1 -stable review patch.  If anyone has any objections, please let me know.

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

From: Nikola Pajkovsky <npajkovs@redhat.com>

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.
