hwmon: (asus_wmi_ec_sensors) fix array overflow
Smatch detected an array out of bounds error:
drivers/hwmon/asus_wmi_ec_sensors.c:562 asus_wmi_ec_configure_sensor_setup()
error: buffer overflow 'hwmon_attributes' 8 <= 9
The hwmon_attributes[] array needs to be declared with "hwmon_max"
elements.
Fixes: c04c7f7bfcbe ("hwmon: (asus_wmi_ec_sensors) Support B550 Asus WMI.")
