Log:
  Stop "nfsstat -z" from clearing counts of NFSv4 state structures.
  
  The "-z" option on nfsstats was erroneously zeroing out the counts
  of NFSv4 state structures. These counts will normally go back down
  to zero as state is released. When zeroed out by "-z", these counts
  can go negative. This patch fixes this problem.
