Reset the number of HWC layers on failures before HWC prepare
Observed that for the first frame after boot, PrepareLayerList() is successful hence number of HWC layers > 0 but it lands in "FBSurface not initialized" failure in TryHwComposition() and fall back to GPU Composition. Subsequently, in Render(), the decision to call Prepare() is based on the number of HWC layers. Hence, hwc set gets called without prepare. So, reset the number of HWC layers on any failure before prepare.
