ocfs2: harden buffer check during mapping of page blocks
We don't want to submit buffer_new blocks for read i/o. This actually won't happen right now because those requests during an allocating write are all nicely aligned. It's probably a good idea to provide an explicit check though. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
