Host mode Client exits the game and reports an error

[heartzwh]

When the Client in Host mode is disconnected, LightReflectiveMirrorTransport._isClient = false will be executed first. When LightReflectiveMirrorTransport.DataReceived is executed and opcode == ServerLeft _isClient is already equal to false, the OnClientDisconnected event cannot be called normally.
