ocfs2: inconsequent NULL checking

From: Adrian Bunk

The Coverity checker spotted the following inconsequent NULL checking in
fs/ocfs2/dlmglue.c:

<-- snip -->

...
int ocfs2_meta_lock_atime(struct inode *inode,
struct vfsmount *vfsmnt,
int *level)
{
...
if (ocfs2_should_update_atime(inode, vfsmnt))
ocfs2_update_inode_atime(inode, bh);
if (bh)
brelse(bh);
...

<-- snip -->

Since commit c11e9fafb398411af7558fca913c2fa4a10b1f48
ocfs2_update_inode_atime() contains an unconditional
dereference of "bh".
