Fix crash when clicking in window while Blender starts

A mouse click in the window will trigger the `VIEW3D_OT_cursor3d` operator
before the viewport is available. This causes a segfault in
`GPU_viewport_engines_data_validate()`.

Other callers of `WM_draw_region_get_viewport()` already check for `NULL`
being returned and handle it gracefully.
