Fix full draw power usage increase issue

Browse Source 
Full draw will be happened on HWUI under 90/120Hz device,there are
more draw commands under renderFrameImpl than in the 60Hz fps device,
frame.bufferAge() > (int)mSwapHistory.size() resulting in an increase
in power usage.

So need to increase (int)mSwapHistory.size() to 8, set mSwapHistory
add to 7.
