[PATCH] ntoskrnl.exe: Force driver name to lowercase.

[Rémi Bernon]

For instance winebus driver is sometimes referred as WineBus, when
loaded by winedevice.exe, and sometimes as winebus, when loaded from
devices. This makes Wine try to load it twice and initializes the
backend twice as well.

It happened to me while forcing hidraw driver to be loaded before SDL.
It's causes winebus to be loaded twice and created two devices for each
HID device.
