Subject: ocfs2: use actual name length when find entry in ocfs2_orphan_del()

ocfs2: use actual name length when find entry in ocfs2_orphan_del()

If the namelen is 20 and name only has actual length 16, it will fail in
ocfs2_find_entry because of mismatch.  So use actual name length when find
entry.
