Attempt ROLLBACK when context is canceled. If ROLLBACK fails, return driver.ErrBadConn to discard the connection. Closes raimeecas#2

When context is canceled during BeginTx, the connection may have an active transaction on the server. This fix attempts a ROLLBACK first, and if that fails (context expired), returns driver.ErrBadConn so database/sql discards the connection instead of recycling it. Closes #2.
