Commit 2d99925a15b6 ("hwmon: (nct6775) Separate fan/pwm configuration
detection for NCT6793D") accidentally removed part of the code detecting
if fan6 is enabled or not. As result, fan6 is no longer detected on Asus
PRIME Z370-A. Restore the missing detection code.
Fixes: 2d99925a15b6 ("hwmon: (nct6775) Separate fan/pwm configuration
detection for NCT6793D")
