net: ethernet: aquantia: call set_irq_affinity_hint before free_irq

When a network interface controlled by the aquantia ethernet driver is brought
down a warning is output in dmesg (see below).

The problem is that aq_pci_func_free_irqs() is calling free_irq() before it is
calling irq_set_affinity_hint().
