Subject: [PATCH] ocfs2/dlm: remove redundant assignment to ret

From: Colin Ian King <colin.king@...onical.com>

The variable ret is being initialized with a value that is never
read and it is being updated later with a new value.  The initialization
is redundant and can be removed.

Addresses-Coverity: ("Unused value")
