Subject: [PATCH] LibWeb: Don't call flush() when no surface is passed in
 execute_impl()

`DisplayListPlayer::execute_impl()` can receive null surface if it was
invoked to rasterize nested display lists (we use them for iframes). In
this case we should not call `flush()` by the end of execution and wait
until outer display list execution will do that.
