NFSD: Fix nfsd_clid_class use of __string_len() macro
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.
