layout: Remove explicit damage call

layout: Remove explicit damage call

As we will be marking all the views dirty, weston_output_repaint()
should pick-up correctly any inflicted damage, and perform an
implicit redraw without the need for an explict to call to
weston_view_below_damage().

Note that we still need to schedule a repaint for that particular view.

While at it, also remove an explicit call to
weston_view_update_transform() which is going to be handled internally
as well, when rebuilding the view list by libweston.
