x86/hvm: pv-on-hvm: fix de/assert_irq checks
The checks in assert_irq and deassert_irq to distinguish interrupts
that have been remapped onto event channels from the others that have
to be injected using the emulated lapic are wrong.
Fix the condition checks using the convenient hvm_domain_use_pirq
function.
