Guenter Roeck f107cee94b genirq: Unlock irq descriptor after errors
In irq_set_irqchip_state(), the irq descriptor is not unlocked after an
error is encountered. While that should never happen in practice, a buggy
driver may trigger it. This would result in a lockup, so fix it.

Fixes: 1d0326f352 ("genirq: Check irq_data_get_irq_chip() return value before use")
