SUNRPC: Use correct XDR encoding procedure for rpcbind SET/UNSET

The rpcbind versions 3 and 4 SET and UNSET procedures use the same
arguments as the GETADDR procedure.

While definitely a bug, this hasn't been a problem so far since the
kernel hasn't used version 3 or 4 SET and UNSET.  But this will change
in just a moment.
