Subject: Fix /proc/net/packet crash due to bogus private pointer
From: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx>
The seq_open_net patch changed the meaning of seq->private. Unfortunately
it missed two spots in AF_PACKET, which still used the old way of
dereferencing seq->private, thus causing weird and wonderful crashes when
reading /proc/net/packet.
This patch fixes them.
