hwmon: (coretemp) Fix harmless build warning

Fix the following build warning:

  CC [M]  drivers/hwmon/coretemp.o
drivers/hwmon/coretemp.c: In function "coretemp_init":
drivers/hwmon/coretemp.c:521: warning: unused variable "n"
drivers/hwmon/coretemp.c:521: warning: unused variable "p"

Introduced by commit 851b29cb. When
you drop code, you also have to drop the variables this code was
using.
