[PATCH] hwmon/applesmc: Fix uninitialized variables warnings

[Shuah Khan]

Fix the following "maybe used uninitialized" warnings by
initializing the variables to keep the compiler quiet.
There is no "used uninitialized" in this case.

  CC [M]  drivers/hwmon/applesmc.o
drivers/hwmon/applesmc.c: In function âapplesmc_init_smcregâ:
drivers/hwmon/applesmc.c:595:43: warning: âright_light_sensorâ
may be used uninitialized in this function [-Wmaybe-uninitialized]
  s->num_light_sensors = left_light_sensor + right_light_sensor;
                                           ^
drivers/hwmon/applesmc.c:540:26: note: âright_light_sensorâ was
declared here
  bool left_light_sensor, right_light_sensor;
                          ^
