KVM: x86: Isolate edge vs. level check in userspace I/O APIC route scanning 



Extract and isolate the trigger mode check in kvm_scan_ioapic_routes() in
anticipation of moving destination matching logic to a common helper (for
userspace vs. in-kernel I/O APIC emulation).

No functional change intended.
