Subject: [PATCH] [hwcomposer] Use newer setOutputsEnabled API instead of
 blocking buffer swap

The newer API is designed for the case that outputs are disabled and
makes sure that we don't have to abuse the aboutToSwapBuffers. This
also prevents possible conflicts between blocking during rendering and
screens being off.
