ocfs2: Use __generic_file_aio_write instead of generic_file_aio_write_nolock
Use the new helper. We have to submit data pages ourselves in case of O_SYNC write because __generic_file_aio_write does not do it for us. OCFS2 developpers might think about moving the sync out of i_mutex which seems to be easily possible but that's out of scope of this patch.
