Check the frame for null only if the reader is null

This change moves the frame check inside the reader check to address
cases when GamepadSharedMemoryReader::Start() is called again after
Stop(), but the frame is null. Since the frame parameter is only used
when creating a new instance of GamepadSharedMemoryReader, the check was
moved inside the corresponding condition.
