KVM: x86: fix *NULL on invalid low-prio irq

Smatch noticed a NULL dereference in kvm_intr_is_single_vcpu_fast that
happens if VM already warned about invalid lowest-priority interrupt.

Create a function for common code while fixing it.

Fixes: 6228a0da8057 ("KVM: x86: Add lowest-priority support for vt-d posted-interrupts")
