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.
