hwmon: (hp-wmi-sensors) fix debugfs check

Checking for Kconfig symbols with #if is wrong:

drivers/hwmon/hp-wmi-sensors.c:1141:5: error: "CONFIG_DEBUG_FS" is not defined, evaluates to 0 [-Werror=undef]

This could be an #ifdef, but an IS_ENABLED() check is even better to
give the best compile coverage.
