Subject: [PATCH] ocfs2: remove deadcode on variable tmp_oh check

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

At the end of cfs2_inode_lock_tracker tmp_oh is true because an
earlier check on tmp_oh being false returns out of the function.
Since tmp_oh is true, the function will always return 1 so remove
the redundant check and return of 0.

Addresses-Coverity: ("Logically dead code")
