Wang,Fei 10f57b73f3 msdk: vpp: remove mfxExtVPPDoUse from vpp filters. 
According to msdk spec, there are two ways to enable filters:
1: Filters can be enabled by adding a filter ID
to mfxExtVPPDoUse. In this case, default filter parameters are used
2: Add filter configuration structures directly to mfxVideoParam.

Using 1 with 2 is optional but legal. Unfortunately it won't work
with some specific use cases like Detail/EdgeEnhancement.
Let's stick with option2 which works fine for all VPP operations.
