PAD: Fix dualshock lights for more than one controller attached

[AKuHAK]

Codacy warnings fixed

Description of Changes

Currently only first controller correctly handles lights, this pr fixes it

Rationale behind Changes

Suggested Testing Steps

[refractionpcsx2]

uhh, that's a hack, it just makes all the sendState.lights values underflow, which is not a desired behaviour.

Go back and try to find the real problem and fix that. I believe you were close
