[Ocfs2-devel] [PATCH] indexed-dirs: fix brelse order in ocfs2_find_entry_dx()

[Coly Li <coly.li@suse.de>]

In ocfs2_find_entry_dx(), if ocfs2_read_inode_block() failed, both di_bh and dx_root_bh are both released. In this case,
for dx_root_bh, it's unnecessary (even buggy if refcount of dx_root_bh is non-zero).

This patch fixes this issue by change brelse order of di_bh and dx_root_bh.
