[win32k]
- In reactos when an application tries to use a desktop or window station object we never
check if it should have access to the object. However the only exception to this is
NtUserGetObjectInformation. Since desktops and windows stations are a mess,
NtUserGetObjectInformation always fails. Ironically windows do such access checks
everywhere except NtUserGetObjectInformation. Fix NtUserGetObjectInformation by removing
access checks
- Note: access checks for every other place will be fixed soon
