NFSD: Add nfsd_clid_confirmed tracepoint
This replaces a dprintk call site in order to get greater visibility
on when client IDs are confirmed or re-used. Simple example:
nfsd-995 [000] 126.622975: nfsd_compound: xid=0x3a34e2b1 opcnt=1
nfsd-995 [000] 126.623005: nfsd_cb_args: addr=192.168.2.51:45901 client 60958e3b:9213ef0e prog=1073741824 ident=1
nfsd-995 [000] 126.623007: nfsd_compound_status: op=1/1 OP_SETCLIENTID status=0
nfsd-996 [001] 126.623142: nfsd_compound: xid=0x3b34e2b1 opcnt=1
>>>> nfsd-996 [001] 126.623146: nfsd_clid_confirmed: client 60958e3b:9213ef0e
nfsd-996 [001] 126.623148: nfsd_cb_probe: addr=192.168.2.51:45901 client 60958e3b:9213ef0e state=UNKNOWN
nfsd-996 [001] 126.623154: nfsd_compound_status: op=1/1 OP_SETCLIENTID_CONFIRM status=0
