hwmon: (abituguru3) Fix CONFIG_DMI=n fallback to probe

When CONFIG_DMI is not enabled, dmi detection should flag that no board
could be detected (err=1) rather than another error condition (err<0).

This fixes the fallback to manual probing for all motherboards, even
those without DMI strings, when CONFIG_DMI=n.
