====================
af_unix: Fix two OOB issues.

From: Kuniyuki Iwashima <kuniyu@google.com>

Recently, two issues are reported regarding MSG_OOB.

Patch 1 fixes issues that happen when multiple consumed OOB
skbs are placed consecutively in the recv queue.

Patch 2 fixes an inconsistent behaviour that close()ing a socket
with a consumed OOB skb at the head of the recv queue triggers
-ECONNRESET on the peer's recv().
