wpa: make sure wpa-ctrl stays around during dispatch
If we call into user-callbacks, we need to make sure that they do not free
the wpa-object. We want to explicitly allow that so take a ref before
calling any callback and drop it afterwards.
We already check for !open so we bail out early if sth fails.
