blast: turn off surface damage

Turn off surface damage because:
1) It is causing P19 devices to not update damaged buffers. This
is probably due to a hwc bug.
2) On early pixel devices, it can cause extra work in hwc which negates
any benefits of using it in the first place. Since most of the video
layers won't have useful surface damage, the extra work isn't worth it.

Test: Full screen Youtube video in Chrome on P19
