Subject: [PATCH] ocfs2: dlmglue: remove redundant check of null tmp_oh

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

A null tmp_oh is already being checked earlier and always leads to
an early return.  Thus the check for a null tmp_oh at the end of
function ocfs2_inode_lock_tracker is redundant and can be replaced
with a return 1 instead.

Detected by CoverityScan, CID#1468855 ("Logically dead code")
