Jens Axboe 4c0b26e23c io_uring: add async data clear/free helpers ...

Futex recently had an issue where it mishandled how ->async_data and
REQ_F_ASYNC_DATA is handled. To avoid future issues like that, add a set
of helpers that either clear or clear-and-free the async data assigned
to a struct io_kiocb.

Convert existing manual handling of that to use the helpers. No intended
functional changes in this patch.
