[PATCH weston v2] compositor: make sure to reset views' pointers to destroyed output

[Giulio Camuffo]

When an output is destroyed reassign the output of the views that
were in it, to be sure not to keep a dangling pointer which could
be used later on by calling weston_surface_assign_output() on the
view's surface.
