Log:
[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
