[Wine-patches] wineusb: Load USB device drivers when it is necessary.

[Alexander Morozov]

Чтобы драйвер не загружался при загрузке wine даже когда нет USB-устройства, 
надо изменить HKLM\System\CurrentControlSet\Services\имя_драйвера\Start на 3 
(SERVICE_DEMAND_START).

dwCurrentState устанавливается в SERVICE_RUNNING, так как иначе StartServiceW 
завершается с ошибкой ERROR_SERVICE_DATABASE_LOCKED.
