Log:
  Don't increment srvrpccnt[] for the NFSv4.1 operations.
  
  When support for NFSv4.1 was added to the NFS server, it broke
  the server rpc count stats, since newnfsstats.srvrpccnt[] doesn't
  have entries for the new NFSv4.1 operations.
  Without this patch, the code was incrementing bogus entries in
  newnfsstats for the new NFSv4.1 operations.
  This patch is an interim fix. The nfsstats structure needs to be
  updated and that will come in a future commit.
