Fix client side hang when describe message is followed by NoData response.

For certain describe request for a query including "LISTEN", NoData
message can be returned. Since Pgpool-II buffered NoData, clients
could hang waiting for the NoData message in vain. To fix this, do not
buffer NoData message.

Problem reported and patch provided by Daniel van de Giessen.
