io_uring: fix short read retries for non-reg files
Sockets and other non-regular files may actually expect short reads to happen, don't retry reads for them. Because non-reg files don't set FMODE_BUF_RASYNC and so it won't do second/retry do_read, we can filter out those cases after first do_read() attempt with ret>0.
