    These USB API functions will do the full authorization/deauthorization
    to be used for a device. When authorized we effectively allow a
    configuration to be set. Reverse that when deauthorized.
    
    Effectively this means that we have to clean all the configuration
    descriptors on deauthorize and reload them when we authorized. We could
    do without throwing them out for wired devices, but for wireless, we can
    read them only after authenticating, and thus, when authorizing an
    authenticated device we would need to read them. So to simplify, always
    release them on deauthorize(), re-read them on authorize().
    
    Also fix leak reported by Ragner Magalhaes; in usb_deauthorize_device(),
    bNumConfigurations was being set to zero before the for loop, and thus
    the different raw descriptors where never being freed.
