nfsd: use nfs client rpc callback program
since commit ff7d9756b501744540be65e172d27ee321d86103
"nfsd: use static memory for callback program and stats"
do_probe_callback uses a static callback program
(NFS4_CALLBACK) rather than the one set in clp->cl_callback.cb_prog
as passed in by the client in setclientid (4.0)
or create_session (4.1).
This patches introduces rpc_create_args.prognumber that allows
overriding program->number when creating rpc_clnt.
