drm: Fix support for PCI domains
(For some reason I thought that went in ages ago ...)
This fixes support for PCI domains in what should hopefully be a backward
compatible way along with a change to libdrm.
When the interface version is set to 1.4, we assume userspace understands
domains and the world is at peace. We thus pass proper domain numbers
instead of 0 to userspace.
The newer libdrm will then try 1.4 first, and fallback to 1.1, along with
ignoring domains in the later case (well, except on alpha of course)
