SurfaceFlinger: fix a layer occlusion bug
This change fixes a bug where the window visibility would be computed
before any buffers were available, causing the window to be treated as
non-opaque. When the first buffer arrived, if both mCurrentOpacity and
the opacity determined by the buffer's format were 'opaque', a
recomputation of the opacity would not be done, and the window would
continue to be treated as non-opaque. SurfaceFlinger could then
unnecessarily draw fully occluded layers.
