hwmon : (applesmc) Fix uninitialized variables warnings

Browse source 
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 ‘applesmc_init_smcreg’:
