vk: Set I915_CACHING_NONE for userptr BOs when !llc

Regular objects are created I915_CACHING_CACHED on LLC platforms and
I915_CACHING_NONE on non-LLC platforms. However, userptr objects are
always created as I915_CACHING_CACHED, which on non-LLC means
snooped. That can be useful but comes with a bit of overheard.  Since
we're eplicitly clflushing and don't want the overhead we need to turn
it off.
