svn commit: r336933 - head/sys/fs/nfsclient

[Rick Macklem]

Author: rmacklem
Date: Mon Jul 30 20:25:32 2018
New Revision: 336933
URL: https://svnweb.freebsd.org/changeset/base/336933

Log:
  Silence newer gcc warnings.
  
  Newer versions of gcc generate "set, but not used" warnings.
  Add __unused macros to silence these warnings.
  Although the variables are not being used, they are values parsed from
  arguments to callback RPCs that might be needed in the future.
