[User Kitagawa]

Log Message:
-----------
Fix bug that SELECT isn't sent to master node when the query meets
the following conditions.

- in MASTER/SLAVE mode
- use extended query protocol
- started transaction explicitly
- after write queries

It's necessary to use REAL_MASTER_NODE macro for the judgement of
whether an query is in the transaction.
