vmwgfx: Fix assignment in vmw_framebuffer_create_handle
commit bf9c05d5b6d19b3e4c9fe21047694e94f48db89b upstream.
The assignment of handle in vmw_framebuffer_create_handle doesn't actually do anything useful and is incorrectly assigning an integer value to a pointer argument. It appears that this is a typo and should be dereferencing handle rather than assigning to it directly. This fixes a bug where an undefined handle value is potentially returned to user-space.
