Bounds check rpcbs_rmtcall(..) to ensure rtype is less than RPCBVERS_STAT

Not returning if rtype == RPCBVERS_STAT will cause us to overrun the inf array, as
it's defined to be exactly RPCBVERS_STAT elements in rpcb_prot.x:

> include/rpc/rpcb_prot.x:typedef rpcb_stat rpcb_stat_byvers[RPCBVERS_STAT];

The proposed change also matches the rest of the rtype upper bound checks in the
file, so the original change was likely a typo.
