Subject: [PATCH v2 net-next 00/12] af_unix: Prepare for skb drop reason.

This is a prep series and cleans up error paths in the following
functions

  * unix_stream_connect()
  * unix_stream_sendmsg()
  * unix_dgram_sendmsg()

to make it easy to add skb drop reason for AF_UNIX, which seems to
have a potential user.

    * Drop previous patch 4, 7, 14
    * Patch 4
      * Move send_sig() after SEND_SHUTDOWN check before goto
