hwmon: (dell-smm) Fix off-by-one error in dell_smm_is_visible()

The documentation states that on machines supporting only global
fan mode control, the pwmX_enable attributes should only be created
for the first fan channel (pwm1_enable, aka channel 0).

Fix the off-by-one error caused by the fact that fan channels have
a zero-based index.
