drm/i915/dpt: Make DPT object unshrinkable

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

drm/i915/dpt: Make DPT object unshrinkable

In some scenarios, the DPT object gets shrunk but
the actual framebuffer did not and thus its still
there on the DPT's vm->bound_list. Then it tries to
rewrite the PTEs via a stale CPU mapping. This causes panic.
