[ Upstream commit 7b08cf62b1239a4322427d677ea9363f0ab677c6 ]
The double copy of the string is a mistake, plus __assign_str()
uses strlen(), which is wrong to do on a string that isn't
guaranteed to be NUL-terminated.
Fixes: 6019ce0742ca ("NFSD: Add a tracepoint to record directory entry encoding")

Clean up: These are noise in properly working systems. If you really
need to observe the operation of the callback mechanism, use the
sunrpc:rpc\* tracepoints along with the workqueue tracepoints.

Renamed so it can be enabled as a set with the other nfsd_cb_
tracepoints. And, consistent with those tracepoints, report the
address of the client, the client ID the server has given it, and
the state ID being recalled.
