[GDI32] Fix GetObjectW() GDI_OBJECT_TYPE_BRUSH handling. (#4394)

This fixes the last GetObjectW apitest case:
    ok_long(GetObjectA(hBrush, 0, &TestStruct), 0);

- When "cbSize" is "0", GetObjectW shouldn't return "sizeof(LOGBRUSH)" but 0.
    - Rely in BRUSH::cjGetObject behavior which returns 0 when cjSize is 0.
