  Modified files:
    sys/netgraph         ng_base.c 
  Log:
  Fix an item leak, that happens when some node calls ng_callout() two
  times consequently, without checking whether callout has been serviced
  or not. (ng_pptpgre and ng_ppp were catched in this behavior).
  
    - In ng_callout() save old item before calling callout_reset(). If the
      latter has returned 1, then free this item.
    - In ng_uncallout() clear c->c_arg.
