[pgpool-committers: 3784] pgpool: Fix do_query() hangs after close message.

[Tatsuo Ishii]

Fix do_query() hangs after close message.

This is an en-bug in 3.6.1.

If an extend query appears right after a close message, do_query() is
called to check system catalogs, it hangs because it expects to read
pending data. This is caused by being mistakenly set the pending flag
after Close().

Back patch to 3.6-stable and 3.5-stable.
