Don't send data if display is disconnected

Browse Source 
Otherwise, we're waiting 1s on pretty much any call to the display. If
the display gets disconnected at the start of the `update_display()`
function, that can mean quite the delay.

It's possible that this delay triggers a watchdog timer that blinks the
LEDs, but there doesn't appear to be any watchdog timer configured.
