[ Upstream commit 7bc36e3ce91471b6377c8eadc0a2f220a2280083 ]

Fixes gcc '-Wunused-but-set-variable' warning:

  fs/ocfs2/xattr.c: In function ocfs2_xattr_bucket_find:
  fs/ocfs2/xattr.c:3828:6: warning: variable last_hash set but not used 
[-Wunused-but-set-variable]

It's never used and can be removed.
