drm/i915: Add __rcu annotation to cursor when iterating client objects

Browse source 
__rcu annotation is needed to avoid the sparse warnings such as:

  .../i915_drm_client.c:92:9: sparse: sparse: incompatible types in comparison expression (different address spaces):
  .../i915_drm_client.c:92:9: sparse:    struct list_head [noderef] __rcu *
  .../i915_drm_client.c:92:9: sparse:    struct list_head *
