io_uring: import_single_range() returns 0/-ERROR
Unlike the other core import helpers, import_single_range() returns 0 on success, not the length imported. This means that links that depend on the result of non-vec based IORING_OP_{READ,WRITE} that were added for 5.5 get errored when they should not be. Fixes: 3a6820f2bb8a ("io_uring: add non-vectored read/write commands") Signed-off-by: Jens Axboe <axboe@kernel.dk>
