drm/i915: Add __rcu to radix tree slot pointer
radix_tree_for_each_slot() wants an __rcu annotated pointer for the
slot. So let's add the annotation.
Fixes the following sparse warnings:
i915_gem.c:2217:9: warning: incorrect type in assignment (different address spaces)
i915_gem.c:2217:9: expected void **slot
i915_gem.c:2217:9: got void [noderef] <asn:4>**
