io_uring: remove superfluous check for sqe->off in io_accept()
This field contains a pointer to addrlen and checking to see if it's set returns -EINVAL if the caller sets addr & addrlen pointers. Fixes: 17f2fe35d080 ("io_uring: add support for IORING_OP_ACCEPT") Signed-off-by: Hrvoje Zeba <zeba.hrvoje@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
