Kuniyuki Iwashima 1971d13ffa af_unix: Suppress false-positive lockdep splat for spin_lock() in __unix_gc(). 
syzbot reported a lockdep splat regarding unix_gc_lock and
unix_state_lock().

One is called from recvmsg() for a connected socket, and another
is called from GC for TCP_LISTEN socket.

So, the splat is false-positive.

Let's add a dedicated lock class for the latter to suppress the splat.

Note that this change is not necessary for net-next.git as the issue
is only applied to the old GC impl.
