Jens Axboe 985b71db17 iomap: use filemap_range_needs_writeback() for O_DIRECT reads
For reads, use the better variant of checking for the need to call
filemap_write_and_wait_range() when doing O_DIRECT.  This avoids falling
back to the slow path for IOCB_NOWAIT, if there are no pages to wait for
(or write out).
