  -----------
  fix sending of I2C errors via telemetry
* we can't pass the address of a volatile var to the downlink macros:
  it will be cast to (const uint8_t*) and read byte by byte and hence not work 
properly if it is volatile
* you will also rightly get a warning "cast discards qualifiers from pointer 
target type"
* so we need to copy it to a non-volatile var before sending
