Log the format when mmapping the sound device

[Francois Gouget]

For many sound devices the mmap fails if the sound device is not in just 
the right format. This is known to happen on many i810 sound devices, 
but also for via8233+Alsa in OSS emulation mode (though it wasn't always 
like this).
The upshot is that when debugging DirectSound problems it's critical to 
know what's the format of the sound device when an mmap succeeds or fails.

    Log the format when mapping the sound device (or failing to).
