pad: Don't consider flushing pads as needing reconfiguration

Browse source 
Renegotiation and reconfiguration will fail because all queries
and events won't be accepted by the pad if it's flushing. In the
best case this just causes unneeded work and spurious warnings in
the debug logs, in the worst case it causes elements to fail completely.
