svcrpc: fix UDP on servers with lots of threads
James Pearson found that an NFS server stopped responding to UDP
requests if started with more than 1017 threads.
sv_max_mesg is about 2^20, so that is probably where the calculation
performed by
svc_sock_setbufsize(svsk->sk_sock,
(serv->sv_nrthreads+3) * serv->sv_max_mesg,
(serv->sv_nrthreads+3) * serv->sv_max_mesg);
starts to overflow an int.
