Commit message:
Print error instead of killing the microcontroller.

Temperature sensors failing should not cause the entire system to fail.
The Mbed `error` function calls `exit(0)` and causes everything else to
stop working.

My testing with 7 DS18B20 sensors has shown that just ignoring this error
and searching again works fine.
