[ALSA] aoa: feature gpio layer: fix IRQ access

The IRQ rework caused some hiccups here, in some cases we call
get_irq without a device node. This patch makes it catch that
case and return NO_IRQ when it happens, along with changing the
place where the irq is checked to check for NO_IRQ instead of -1.
