Subject: [PATCH] SurfaceFlinger: mFbFence initialization

MobC00383030
b/12487813

SurfaceFlinger crash is observed while connecting
to Wi-Fi display.

Note: change 14e8b01a761180250671f3d6494532d8bd04fa8e
removed the initialization leading to the crash when
running through the HWC composition path.  Restore the
initialization to solve the problem.
