Fix a couple of minor bugs in the new MCIWnd code

[Dmitry Timoshkov]

Hello,

Changelog:
    Dmitry Timoshkov <dmitry at codeweavers.com>
    Trackbar range should be fixed only in the case of successful
    mciSendStringW. It's better to initialize dwCallback parameter
    if MCI_NOTIFY is specified.
