Fixes the following error when attempting to add a disk with bus='virtio'
to a machine which actually supports virtio-mmio (caught with ARM virt):
virtio disk cannot have an address of type 'virtio-mmio'
The problem has been likely introduced by
e8d55172544c1fafe31a9e09346bdebca4f0d6f9. Before that
qemuAssignDevicePCISlots() was never called for ARM "virt" machine.

v1 => v2
- Added check for QEMU_CAPS_DEVICE_VIRTIO_MMIO, this leaves the
error message for machines which actually do not support
virtio-mmio. In this case the user may still attempt to add
such a disk manually.

There is no qemuCaps here, you have to pas it the whole way.
