Fixes an error where the hdzero and skyzone backpacks would read a MSP message (response) from the VRx and would not mark the message as received. This then left the MSP processor in the RECEIVED state. The next character pushed into the processor would be ignored, but put it into IDLE state, so the next whole message is discarded.
This manifests itself as alternate message would be processed.
