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)
