Log:
  Add call to svcpool_close() for the NFSv4 callback pool (svcpool_nfscbd).
  
  A function called svcpool_close() was added to the server side krpc by
  r313735, so that a pool could be closed without destroying the data structures.
  This little patch adds a call to it for the callback pool (svcpool_nfscbd),
  so that the nfscbd daemon can be killed/restarted and continue to work
  correctly.
