Noticed while doing a depth-first search for a different refactor.

ACK series We should drop QEMU_CAPS_DEVICE from all of libvirt code since this capability will be always set. Maybe also add a syntax-check to forbit to use QEMU_CAPS_DEVICE outside of src/qemu/qemu_capabilities.h. Pavel

The way we have been doing that is to change the name to X_QEMU_CAPS_DEVICE once all uses are removed, so it will stick out in newly added code. And if anyone is motivated, I documented a bunch of other old flags that can be dropped: http://wiki.libvirt.org/page/BiteSizedTasks#Remove_unused_QEMU_feature_flags - Cole
