fa2662c293 net: Avoid logging AlreadyHaveTx when disconnecting misbehaving peer (MarcoFalke)

Pull request description:

  There is no need to log `AlreadyHaveTx` for an inv when a peer is marked for disconnection due to sending that inv. In fact, I find it confusing that a `block-relay-only` connection calls `AlreadyHaveTx` at all. Also there is no need to call `AddKnownTx` when the peer is marked for disconnection.
