xen: domain_pirq_to_emuirq return IRQ_UNBOUND by default
domain_pirq_to_emuirq should return IRQ_UNBOUND rather than 0 on
missing entries. Add a default parameter to pirq_field, so that
callers can set any default return value they want; use IRQ_UNBOUND in
domain_pirq_to_emuirq.
This patch fixes a regression introduced by 23573: save/restore
failing on upstream QEMU with PV on HVM guests.
