p2p: Ignore non-version msgs before version msg

Browse source 
Sending a non-version message before the initial version message is peer
misbehavior. Though, it seems arbitrary and confusing to disconnect only
after exactly 100 non-version messages. So remove the Misbehaving and
instead rely on the existing disconnect-due-to-handshake-timeout logic.
