[PATCH] NFSD: Fix nfsd_clid_class use of __string_len() macro

[Steven Rostedt <rostedt@goodmis.org>]

From: "Steven Rostedt (Google)" <rostedt@goodmis.org>

I'm working on restructuring the __string* macros so that it doesn't need
to recalculate the string twice. That is, it will save it off when
processing __string() and the __assign_str() will not need to do the work
again as it currently does.

Currently __string_len(item, src, len) doesn't actually use "src", but my
changes will require src to be correct as that is where the __assign_str()
will get its value from.

The event class nfsd_clid_class has:

  __string_len(name, name, clp->cl_name.len)

But the second "name" does not exist and causes my changes to fail to
build. That second parameter should be: clp->cl_name.data.

Fixes: d27b74a8675ca ("NFSD: Use new __string_len C macros for nfsd_clid_class")
