svn commit: r334902 - head/sys/fs/nfs

[Rick Macklem]

Author: rmacklem

New Revision: 334902
URL: https://svnweb.freebsd.org/changeset/base/334902

Log:
  Delete an unused macro and clean up a comment about it.
  
  NFSDEV_MIRRORSTR was defined for the pNFS server, but has not been used,
  so this patch deletes it. It also cleans up the comment and hopefully
  makes it more readable.
