All qemu versions we support have QEMU_CAPS_DEVICE, so checking
for it is redundant. Remove the usage.

The code diff isn't clear, but all that code is just inindented
with no other change.

Test cases that hit qemuDomainAssignAddresses but don't have
infrastructure for specifying qemuCaps values see lots of
churn, since now PCI addresses are in the XML output.

Kind of. Prior to patch #2, the test suite output was correct (no addresses),
it's what we were returning via domxml-from-native. After patch #2, the test
suite output was wrong for all real world usage; it didn't change because it
was only hitting a !QEMU_CAPS_DEVICE code path

So the potentially contentious bit is that patch #2 changes domxml-from-native
output to contain addresses, however that's exactly the same result that will
happen when the XML would eventually be defined anyways, so it's effectively
the same result as pre-patch #2 anyways. If we think of domxml-from-native as
telling the user 'this is exactly what libvirt thinks that command line is'
then we are now giving more accurate results

Let me know if that still warrants the ACK

Thanks,
Cole
