Miguel Ojeda 26a2c54d03 auxdisplay: img-ascii-lcd: Silence 2 uninitialized warnings ...

The warnings are:

  drivers/auxdisplay/img-ascii-lcd.c: warning: 'err' may be used
  uninitialized in this function [-Wuninitialized]

At lines 109 and 207. Reported by Geert using the build service
several times, e.g.:

  https://lkml.org/lkml/2018/2/19/303

They are two false positives, since num_chars > 0 in the three present
configurations (boston, malta, sead3). Initialize to 0 in order to
silence the warning.
