cifs: fix the race in cifs_writev() O_APPEND handling there hadn't been completely fixed by Pavel's patch; it checks the right value, but it's racy - we can't really do that until i_mutex has been taken. Fix by switching to __generic_file_aio_write() (open-coding generic_file_aio_write(), actually) and pulling mutex_lock() above inode_size_read().
