p2p: Ignore version msgs after initial version msg
Sending a version message after the intial version message is peer
misbehavior. Though, it seems arbitrary and confusing to disconnect only
after exactly 100 version messages. Duplicate version messages affect us
no different than any other unknown message. So remove the Misbehaving
and ignore the redundant msgs.
