  SVN rev 223749 on 2011-07-04 00:45:21Z by rmacklem
  
  MFC: r223312
  Fix a number of places where the new NFS server did not
  lock the mutex when manipulating rc_flag in the DRC cache.
  This is believed to fix a hung server that was reported
  to the freebsd-fs@ list on June 9 under the subject heading
  "New NFS server stress test hang", where all the threads
  were waiting for the RC_LOCKED flag to clear.
