When we queue a request via tw for execution it's not going to be
executed immediately, so when io_queue_async() hits IO_APOLL_READY
and queues a tw but doesn't try to recycle/consume the buffer some other
request may try to use the the buffer.

Fixes: c7fb1942 ("io_uring: add support for ring mapped supplied buffers")
