drm/i915: Fix one wrong caching mode enum usage

Commit a4d86249c773 ("drm/i915/gt: Provide a utility to create a scratch
buffer") mistakenly passed in uapi I915_CACHING_CACHED as argument to
i915_gem_object_set_cache_coherency(), which actually takes internal
enum i915_cache_level.

No functional issue since the value matches I915_CACHE_LLC (1 == 1), which
is the intended caching mode, but lets clean it up nevertheless.
