Subject: Clarify docs for driver_async() return value

The documentation for driver_async() still referred to the return value of
the function as a "handle", which is no longer meaningful since
driver_async_cancel() was deprecated and removed. Modify the documentation
to simply indicate that the driver_async() return value will be -1 if it
fails.
