netlink: eliminate nl_sk_hash_lock
As rhashtable_lookup_compare_insert() can guarantee the process of search and insertion is atomic, it's safe to eliminate the nl_sk_hash_lock. After this, object insertion or removal will be protected with per bucket lock on write side while object lookup is guarded with rcu read lock on read side.
