Subject: [PATCH 7/7] ocfs2: One function call less in user_cluster_connect()
 after error detection

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 21 Feb 2015 20:09:00 +0100

The kfree() function was called by the user_cluster_connect() function
even if a previous call of the kzalloc() function failed.

Return from this implementation directly after failure detection.
