NFSD: Fix TP_printk() format specifier in nfsd_clid_class
Since commit 9a6944fee68e ("tracing: Add a verifier to check string
pointers for trace events"), which was merged in v5.13-rc1,
TP_printk() no longer tacitly supports the "%.*s" format specifier.
These are low value tracepoints, so just remove them.
Reported-by: David Wysochanski <dwysocha@redhat.com>
Fixes: dd5e3fbc1f47 ("NFSD: Add tracepoints to the NFSD state management code")
