ALSA: atmel/ac97c: correct the unexpected behavior when using uninitial value for reset pin

When pdata->reset_pin is passed with a negative value (means gpio
is invalid), then chip->reset_pin will not be assigned to a vaule,
it will use default value 0. This will cause unexpected behavior.

So, add this patch to correct.
