    sound: Fix min/max rate for SNDCTL_AUDIOINFO and SNDCTL_ENGINEINFO
    
    Since we allow feeding of any rate within the [feeder_rate_min,
    feeder_rate_max] range, report this as the min/max rate as well. Only
    exceptions are when we the device is opened in exclusive or bitperfect
    mode.
