Subject: KVM: arm/arm64: vgic-irqfd: Fix MSI entry allocation

From: Marc Zyngier <marc.zyngier@arm.com>

commit 150009e2c70cc3c6e97f00e7595055765d32fb85 upstream.

Using the size of the structure we're allocating is a good idea
and avoids any surprise... In this case, we're happilly confusing
kvm_kernel_irq_routing_entry and kvm_irq_routing_entry...
