Stolen memory is always allocated as physically contiguous pages, mark
the object flags as such.

Are all stolen objects always contiguous or only ones allocated by
i915_gem_object_create_stolen_for_preallocated? If former should
__i915_gem_object_create_stolen just set the flag without the need to
pass it in?
