io_uring: clean up io_queue_next()

Browse source

Move fast check out of io_queue_next(), it makes req->flags checks in
__io_submit_flush_completions() a bit clearer and grants us better
comtrol, e.g. can remove now not justified unlikely() in
__io_submit_flush_completions(). Also, we don't care about having this
check in io_free_req() as the function is a slow path and
io_req_find_next() handles it correctly.
