Gets the result of @task as an integer (#gssize).
If the task resulted in an error, or was cancelled, then this will instead return -1 and set @error.
Since this method transfers ownership of the return value (or error) to the caller, you may only call it once.
Return: the task result, or -1 on error
GException on failure.
