Surprise surprise. The namespace seq patch missed two spots in
AF_PACKET.
[PACKET]: Fix /proc/net/packet crash due to bogus private pointer
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.
