af_unix: Replace garbage collection algorithm.
commit 4090fa373f0e763c43610853d2774b5979915959 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.
