Fix is_set_transaction_serializable() when

SET default_transaction_isolation TO 'serializable'.

SET default_transaction_isolation TO 'serializable' is sent to
not only primary but also to standby server in streaming replication mode,
and this causes an error. Fix is, in streaming replication mode,
SET default_transaction_isolation TO 'serializable' is sent only to the
primary server.

See bug 191 for related info.
