drm/xe/vm: Remove restriction that all VMs must be faulting if one is

With this restriction, all VMs on the device must be faulting VMs if there
is already one faulting VM, in which case the device is considered in
fault mode. This prevents for example an application from running 3D jobs
for the compositor while submitting a SVM compute job on the same device.

Now that mutual exclusion of faulting LR jobs and dma fence jobs is
ensured on the hw engine group, remove this restriction to allow running
faulting and non-faulting VMs on the same device.
