ivi-layout: apply opacity to weston_view correctly 

update_opacity is only called when a ivi-surface is visible. But the
previous code also checks event masks redundantly. However if the event
happens when ivi-surface is invisible, opacity is not calculated. This
patch removes this redundant check to fix potential bug.
