net: mark TransportSerializer/m_serializer as const

Browse Source 
The (V1)TransportSerializer instance CNode::m_serializer is used from
multiple threads via PushMessage without protection by a mutex. This
is only thread safe because the class does not have any mutable state,
so document that by marking the methods and the object as "const".
