[reactos] 02/02: [VIDEOPRT] Fix updating of new registry path values

Therefore we need to update the setting in that key, even when the key already exists. This seems to work good and not cause any issues, but testing indicated that on Windows some values are only updated, when the driver has changed. If neccessary, this can be achieved by updating and querying the ActiveService value in the device enum key (e.g. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_80EE&DEV_BEEF&SUSYS_00000000&REV_00\3&267a616a&0&10\Control: ActiveService).
