vm/qubesvm: handle libvirt reporting domain already dead when killing

Browse Source 
If domain die when trying to kill it, qubesd may loose a race and try to
kill it anyway. Handle libvirt exception in that case and conver it to
QubesVMNotStartedError - as it would be if qubesd would win the race.

Fixes QubesOS/qubes-issues#3755
