hwmon: (asus_wmi_sensors) fix an array overflow

Smatch detects this array overflow:

    drivers/hwmon/asus_wmi_sensors.c:569 asus_wmi_configure_sensor_setup()
    error: buffer overflow 'hwmon_attributes' 8 <= 9

The hwmon_attributes[] array should have "hwmon_max" so that it gets
larger when more attributes are added.
