drm/xe: Reject page faults from non-fault-mode scratch VMs

In the Linux kernel, the following vulnerability has been resolved:

drm/xe: Reject page faults from non-fault-mode scratch VMs

Having scratch enabled does not make a VM capable of handling recoverable
page faults. Allowing scratch VMs through the ASID lookup also admits
dma-fence mode VMs.

If such a VM faults on an already valid VMA, the handler reports success
without fixing the fault, causing the GPU to retry indefinitely.

Only allow fault-mode VMs through the ASID lookup. Fault-mode VMs using
scratch remain supported, while faults from 3D VMs are rejected.
