Fixes #3131

Catches the case when the handshake response has come without the packetfilter extension, while it was configured on the agent:

• On caller, if the caller has configured packetfilter, and listener responded without it, reject the connection: this should never happen in case when the listener is in the version that supports packetfilter, while allowing the connection could cause confusion during transmission and some silent runtime errors
• On listener, if the listener configured packetfilter, but the caller did not request it, allow the connection without packetfilter
