NFSD: Add a Call equivalent to the NFSD_TRACE_PROC_RES macros

Browse Source 
Introduce tracing helpers that can be used before the procedure
status code is known. These macros are similar to the
SVC_RQST_ENDPOINT helpers, but they can be modified to include
NFS-specific fields if that is needed later.
