From: Fedora X Ninjas <x at fedoraproject.org>
If the user wants to set one of the slave devices as
the primary output, we shouldn't fail to do so,
we were returning BadMatch which was tripping up
gnome-settings-daemon and bad things ensues.
Fix all the places we use primaryOutput to work
out primaryCrtc and take it into a/c when slave
gpus are in use.
