We were previously pretty cavalier in handling StgAsyncIOResults which
has proven in #25377 to be problematic. We now initialize the
AsyncResult field of the `stg_block_async_void` frame to NULL when
pushing, assert that it is NULL in `awaitRequest` and that it is not
NULL in `stg_block_async_void`.
