[pgpool-committers: 1381] pgpool: Fix target node selection logic when "DEALLOCATE portal|stateme

[Tatsuo Ishii]

Fix target node selection logic when "DEALLOCATE portal|statement".

When "DEALLOCATE portal|statement" is used and last prepared statement
or portal was not found, target node selection map is not
set. Probably this is not actually harmful because prepared statement
or portal was not found is an error case. The bug was there since day
0.

Per Coverity report "1111491 Structurally dead code".
