winecfg: Don't reload winmm for each audio test

Here's a patch to avoid the crash, and a proposal to fix it properly. From the
patch:

    I originally did this so that the user's changes to the Audio tab would
    take effect without having to relaunch winecfg. However, this causes
    crashes with WinMM's internal thread. We should be using MMDevAPI's
    IMMNotificationClient within WinMM to be informed when the device
    default changes. So this commit fixes the crashy behavior, but goes back
    to requiring a winecfg relaunch to have the settings take effect. After
    we implement IMMNotificationClient, we can do this correctly.
