Remove MYSQL_REPLACE_TRX_IN_THD

replaced with that of the 2nd argument. The previous value is
returned through the 3rd argument's buffer, unless it's NULL. When
the buffer is not provided (value NULL) that should mean the caller
restores previously saved association so the current trx has to be
additionally freed from all association with MYSQL.
