rpcb_clnt: RPC_PROGNOTREGISTERED is a permanent error

rpcbind returns RPC_PROGNOTREGISTERED if it knows for certain that an
RPC
program is not supported for a given transport.  This is a permanent and
authoritative error, so the library's rpcbind query API should never
retry the query -- it will only get the same answer.
