Chuck Lever 1035d65446 NFSD: Add tracepoints to report NFSv4 callback completions 
Wireshark has always been lousy about dissecting NFSv4 callbacks,
especially NFSv4.0 backchannel requests. Add tracepoints so we
can surgically capture these events in the trace log.

Tracepoints are time-stamped and ordered so that we can now observe
the timing relationship between a CB_RECALL Reply and the client's
DELEGRETURN Call. Example:

            nfsd-1153  [002]   211.986391: nfsd_cb_recall:       addr=192.168.1.67:45767 client 62ea82e4:fee7492a stateid 00000003:00000001

            nfsd-1153  [002]   212.095634: nfsd_compound:        xid=0x0000002c opcnt=2
            nfsd-1153  [002]   212.095647: nfsd_compound_status: op=1/2 OP_PUTFH status=0
            nfsd-1153  [002]   212.095658: nfsd_file_put:        hash=0xf72 inode=0xffff9291148c7410 ref=3 flags=HASHED|REFERENCED may=READ file=0xffff929103b3ea00
            nfsd-1153  [002]   212.095661: nfsd_compound_status: op=2/2 OP_DELEGRETURN status=0
   kworker/u25:8-148   [002]   212.096713: nfsd_cb_recall_done:  client 62ea82e4:fee7492a stateid 00000003:00000001 status=0
