Pavel Begunkov 9c2ff3f9b5 io_uring: remove io_preinit_req() ... Apart from setting ->ctx, io_preinit_req() zeroes a bunch of fields of a request, from which only ->file_node is mandatory. Remove the function and zero the entire request on first allocation. With that, we also need to initialise ->ctx every time, which might be a good thing for performance as now we're likely overwriting the entire cache line, and so it can write combined and avoid RMW.
