io_uring: retry early for reads if we can poll
Most of the logic in io_read() deals with regular files, and in some ways it would make sense to split the handling into S_IFREG and others. But at least for retry, we don't need to bother setting up a bunch of state just to abort in the loop later. In particular, don't bother forcing setup of async data for a normal non-vectored read when we don't need it. Signed-off-by: Jens Axboe <axboe@kernel.dk>
