move aio queue allocation from io thread to submitting thread
since commit c9f415d7ea2dace5bf77f6518b6afc36bb7a5732, it has been possible that the allocator is application-provided code, which cannot necessarily run safely on io thread stacks, and which should not be able to see the existence of io threads, since they are an implementation detail. instead of having the io thread request and possibly allocate its queue (and the map structures leading to it), make the submitting thread responsible for this, and pass the queue pointer into the io thread via its args structure. this eliminates the only early error case in io threads, making it no longer necessary to pass an error status back to the submitting thread via the args structure.
