Merge #20408: CConnman: move initialization to declaration

9d09132be4 CConnman: initialise at declaration rather than in Start() (Anthony Towns)

Pull request description:

  Ensure nMaxOutboundTotalBytesSentInCycle and nMaxOutboundCycleStartTime are initialized even if CConnman::Start() is not called. Prevents failures in test/fuzz/connman when run under valgrind.

    review ACK 9d09132be4 , checked that we call Start only once and in the same scope where connman is constructed (AppInitMain) 💸
