Gleb Smirnoff ac5dd14182 Fix two races which happen when netgraph is restructuring: 
- Introduce ng_topo_mtx, a mutex to protect topology changes.
  - In ng_destroy_node() protect with ng_topo_mtx the process
    of checking and pointing at ng_deadnode. [1]
  - In ng_con_part2() check that our peer is not a ng_deadnode,
    and protect the check with ng_topo_mtx.
  - Add KASSERTs to ng_acquire_read/write, to make more
    understandible synopsis in case if called on ng_deadnode.
