drm/xe: Invalidate userptr VMA on page pin fault
Rather than return an error to the user or ban the VM when userptr VMA
page pin fails with -EFAULT, invalidate VMA mappings. This supports the
UMD use case of freeing userptr while still having bindings.
Now that non-faulting VMs can invalidate VMAs, drop the usm prefix for
the tile_invalidated member.
v2:
- Fix build error (CI)
v3:
- Don't invalidate VMA if in fault mode, rather kill VM (Thomas)
- Update commit message with tile_invalidated name chagne (Thomas)
- Wait VM bookkeep slots with VM resv lock (Thomas)
v4:
- Move list_del_init(&userptr.repin_link) after error check (Thomas)
- Assert not in fault mode (Matthew)
