Jens Axboe da8fab32a7 io_uring/uring_cmd: ensure that device supports IOPOLL ... commit 03b3d6be73e81ddb7c2930d942cdd17f4cfd5ba5 upstream. It's possible for a file type to support uring commands, but not pollable ones. Hence before issuing one of those, we should check that it is supported and error out upfront if it isn't.
