drm/amdgpu: Update invalid PTE flag setting

Browse Source 
Update the invalid PTE flag setting with TF enabled.
This is to ensure, in addition to transitioning the
retry fault to a no-retry fault, it also causes the
wavefront to enter the trap handler. With the current
setting, the fault only transitions to a no-retry fault.
Additionally, have 2 sets of invalid PTE settings, one for
TF enabled, the other for TF disabled. The setting with
TF disabled, doesn't work with TF enabled.
