KVM: arm/arm64: vgic-irqfd: Fix MSI entry allocation
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...
Fixes: 95b110ab9a09 ("KVM: arm/arm64: Enable irqchip routing")
