b44: Unconditionally enable interrupt routing on reset

Browse Source 
Unconditionally setup the IRQ routing on chip reset.
It's safe to call ssb_pcicore_dev_irqvecs_enable() unconditionally, because
it has internal checks for redundant calls.

This fixes problems where hardware will not come up properly
due to quirks in the enable-bit hardware.
