svn commit: r334586 - head/sys/fs/nfsserver

New Revision: 334586
URL: https://svnweb.freebsd.org/changeset/base/334586

Log:
  Fix a gcc8 warning about a write only variable.
  
  gcc8 warns that "verf" was set but not used. This was because the code
  that uses it is disabled via a "#if 0".
  This patch adds a "#if 0" to the variable's declaration and assignment
  to get rid of the warning.
  This way the code could be re-enabled without difficulty.
