Make ng_mppc to not disable the node in case of multiple packet loss.
Quite often it can be just packet reorder, and killing link in such case
is inconvenient.  Add few sysctl's to control that behavior.

  Ensure that all cases that enqueue a netgraph item for delivery by a
  ngthread properly set the item's depth to 1.  In particular, prior to this
  change if ng_snd_item failed to acquire a lock on a node, the item's depth
  would not be set at all.  This fix ensures that the error code from rcvmsg/
  rcvdata is properly passed back to the apply callback.  For example, this
  fixes a bug where an error from rcvmsg/rcvdata would not previously
  propagate back to a libnetgraph consumer when the message was queued.
