spapr: Simplify spapr_qirq() handling

Currently spapr_qirq(), whic is used to find the qemu_irq for an spapr
global irq number, redirects through the SpaprIrq::qirq method.  But
the array of qemu_irqs is allocated in the PAPR layer, not the
backends, and so the method implementations all return the same thing,
just differing in the preliminary checks they make.

So, we can remove the method, and just implement spapr_qirq() directly,
including all the relevant checks in one place.  We change all those
checks into assert()s as well, since a failure here indicates an error in
the calling code.
