drm/amdgpu/gmc12: Use AMDGPU_PTE_IS_PTE flag for init_pte_flags on GFX12.0

Browse source

This flag seems to work around a "fault priority problem"
and is necessary for handling faults on GFX12.
The kernel seems unable to mitigate retry faults on GFX12
without this flag.

For reference see:
amdgpu_vm_pte_update_flags() that explains the problem
svm_range_get_pte_flags() that uses the flag on GFX12
