memcg: only check memcg_kmem_skip_account in __memcg_kmem_get_cache
__memcg_kmem_get_cache can recurse if it calls kmalloc (which it does if the cgroup's kmem cache doesn't exist), because kmalloc may call __memcg_kmem_get_cache internally again. To avoid the recursion, we use the task_struct->memcg_kmem_skip_account flag. However, there's no need checking the flag in memcg_kmem_newpage_charge, because there's no way how this function could result in recursion, if called from memcg_kmem_get_cache. So let's remove the redundant code.
