4.9-stable review patch. If anyone has any objections, please let me know.

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...
