io_uring/uring_cmd: switch to always allocating async data
Basic conversion ensuring async_data is allocated off the prep path. Adds a basic alloc cache as well, as passthrough IO can be quite high in rate. Tested-by: Anuj Gupta <anuj20.g@samsung.com> Reviewed-by: Anuj Gupta <anuj20.g@samsung.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
