[pgpool-committers: 4727] pgpool: Do not set writing tx flag with SET TRANSACTION READ ONLY.

[Tatsuo Ishii]

Do not set writing tx flag with SET TRANSACTION READ ONLY.

In extended query mode, execute() sets the flag upon completion of
writing queries.  However the flag was set even when SET TRANSACTION
READ ONLY is issued.  Fix this by using
pool_is_transaction_read_only(). This has been already done in simple
query case.
