ctrl2cgi: fix deferred callbacks

Previously handle_reply() was marked as deferred callback unlike soap.py
where it's synchronous function. This seems to be causing issues where
some of the callbacks are not yield properly. Let's move to the
known-to-work semantics of soap.py where async functions are limited to
Trap() class.
