[Libva] [PATCH 2/2] VPP: Initialize the uninitialed surface to avoid NULL GPU buffer

[Zhao Yakui]

Sometimes the surface allocation is deferred. In such case it should be
checked correctly before it is using. Otherwise the corresponding
GPU buffer is NULL.
This is to fix the regression issue reported by XBMC.
