Lizhi Xu e721564d9c ocfs2: fix possible null-ptr-deref in ocfs2_set_buffer_uptodate 
commit 33b525cef4cff49e216e4133cc48452e11c0391e upstream.

When doing cleanup, if flags without OCFS2_BH_READAHEAD, it may trigger
NULL pointer dereference in the following ocfs2_set_buffer_uptodate() if
bh is NULL.
