Restore the clamp on the return value from rpc_dtablesize().. Some programs (eg: ypserv) use this as an indication of how large svc_fdset is in their hand-rolled svc_run() loops. The svc_fdset table is maintained by the rpc library explicitly for compatability with such programs. (It uses a different variable-sized bitmap itself internally)
