[Patch v1] KVM: x86: Initializing all kvm_lapic_irq fields

[Nitesh Narayan Lal <nitesh@redhat.com>]

Previously all fields of structure kvm_lapic_irq were not initialized
before it was passed to kvm_bitmap_or_dest_vcpus(). Which will cause
an issue when any of those fields are used for processing a request.
This patch initializes all the fields of kvm_lapic_irq based on the
values which are passed through the ioapic redirect_entry object.

Fixes: 7ee30bc132c6("KVM: x86: deliver KVM IOAPIC scan request to target vCPUs")
