drm/i915: Never allow userptr into the new mapping types
Commit 4f2a572eda67 ("drm/i915/userptr: Never allow userptr into the
mappable GGTT") made I915_GEM_MMAP_GTT IOCTLs to fail when attempted
on a userptr object in order to protect from a lockdep splat. Later
on, new mapping types were introduced by commit cc662126b413
("drm/i915: Introduce DRM_I915_GEM_MMAP_OFFSET"). Those new mapping
types suffer from the same lockdep splat issue but they now succeed
when tried on top of a userptr object. Fix it.
v2: Don't play with the -ENODEV driver response (Chris)
