ocfs2: direct write will call ocfs2_rw_unlock() twice when doing aio+dio
commit aa1057b3dec478b20c77bad07442318ae36d893c upstream.
ocfs2_file_write_iter() is usng the wrong return value ('written'). This
will cause ocfs2_rw_unlock() be called both in write_iter & end_io,
triggering a BUG_ON.
This issue was introduced by commit 7da839c47589 ("ocfs2: use
__generic_file_write_iter()").

Fixes: 7da839c47589 ("ocfs2: use __generic_file_write_iter()")
