3.13.11.1 -stable review patch. If anyone has any objections, please let me know.
------------------
From: alex chen <alex.chen at huawei.com>
commit f7cf4f5bfe073ad792ab49c04f247626b3e38db6 upstream.
Do not put bh when buffer_uptodate failed in ocfs2_write_block and
ocfs2_write_super_or_backup, because it will put bh in b_end_io.
Otherwise it will hit a warning "VFS: brelse: Trying to free free
buffer".
