wayland: Force an initial focus in meta_wayland_drag_grab_set_focus()

Browse Source 
We want some initial processing, even if the current focus didn't change.
This could be for example the case of starting DnD too close to the window
edge and out of it. At the point start_drag() is called, the current
pointer focus is already NULL, so set_focus() would simply bail out here.
