Could you fix the documentation of rhashtable_init() as well?

[...]
 * struct rhashtable_params params = {
 *      .head_offset = offsetof(struct test_obj, node),
 *      .key_offset = offsetof(struct test_obj, key),
 *      .key_len = sizeof(int),
 *      .hashfn = arch_fast_hash,
 *      .mutex_is_held = &my_mutex_is_held,
 * };
