Kuniyuki Iwashima 5dfd283f46 af_unix: Replace garbage collection algorithm. 
commit 4090fa373f upstream.

If we find a dead SCC during iteration, we call unix_collect_skb()
to splice all skb in the SCC to the global sk_buff_head, hitlist.

After iterating all SCC, we unlock unix_gc_lock and purge the queue.
