net: prevent sending messages in NetEventsInterface::InitializeNode

Now that the queueing of the VERSION messages has been moved out of
`InitializeNode`, there is no need to pass a mutable `CNode` reference any
more. With a const reference, trying to send messages in this method would
lead to a compile-time error, e.g.:

----------------------------------------------------------------------------------------------------------------------------------
...
net_processing.cpp: In member function ‘virtual void {anonymous}::PeerManagerImpl::InitializeNode(const CNode&, ServiceFlags)’:
net_processing.cpp:1683:21: error: binding reference of type ‘CNode&’ to ‘const CNode’ discards qualifiers
 1683 |     PushNodeVersion(node, *peer);
...
