Since introduced, OOB skb holds an additional reference count with no special reason and caused many issues. Also, kfree_skb() and consume_skb() are used to decrement the count, which is confusing. Let's drop the unnecessary skb_get() in queue_oob() and corresponding kfree_skb(), consume_skb(), and skb_unref(). Now unix_sk(sk)->oob_skb is just a pointer to skb in the receive queue, so special handing is no longer needed in GC.
