    core, shard: Make shards inherit main file's O_DIRECT flag if present

            Backport of: http://review.gluster.org/14191

    If the application opens a file with O_DIRECT, the shards'
    anon fds would also need to inherit the flag. Towards this,
    shard xl would be passing the odirect flag in the @flags parameter
    to the WRITEV fop. This will be used in anon fd resolution
    and subsequent opening by posix xl.
