accel: kvm: Fix kvm_type invocation

Browse source 
Prior to commit f2ce39b4f0 a MachineClass kvm_type method
only needed to be registered to ensure it would be executed.
With commit f2ce39b4f0 a kvm-type machine property must also
be specified. hw/arm/virt relies on the kvm_type method to pass
its selected IPA limit to KVM, but this is not exposed as a
machine property. Restore the previous functionality of invoking
kvm_type when it's present.

Fixes: f2ce39b4f0 ("vl: make qemu_get_machine_opts static")
