[PATCH 2/2] incorrect direct io error handling (v7)

Changes against v6: - Handle direct_io failure inside generic_file_direct_write() as it was recommend by Andrew (during discussion v1), and by Nick (during discussion v6). - change comments, make it more clear. - one more time check what __generic_file_aio_write_nolock() always called
