There are 10 users of __irq_domain_alloc_irqs() and only one - IOAPIC -

This splits out __irq_domain_alloc_irqs_data() to make it clear what
IOAPIC does and makes __irq_domain_alloc_irqs() cleaner.
This should cause no behavioral change.

Was or wasn't 0 considered as error code previously?
Oh. I need to clean this up, the idea is since this does not allocate
IRQs, this should return error code and not an irq, I'll make this explicit.
return virq;
out_free_desc:
irq_free_descs(virq, nr_irqs);
return ret;
