atl: Remove freeing of an invalid pointer

[Aleksey Bragin]

Changelog: Don't try to HeapFree a handle returned by LoadResource.

To quote msdn (http://msdn.microsoft.com/en-us/library/ms648046.aspx)  
on this issue:
1. "the return value is a handle to the data associated with the  
resource"
2. "Do not pass this handle to the GlobalLock or GlobalFree function".


With the best regards,
Aleksey Bragin.
