io_uring: simplify io_resubmit_prep() If not for async_data NULL check, io_resubmit_prep() is already an rw specific version of io_req_prep_async(), but slower because 1) it always goes through io_import_iovec() even if following io_setup_async_rw() the result 2) instead of initialising iovec/iter in-place it does it on-stack and then copies with io_setup_async_rw().
