vapostproc: optimization for va memory to system memory only

Browse source 
When the conversion is only caps feature from memory:VAMemory to system memory,
it's possible to optimize by doing a pseudo pass-through since the va-backed
buffers are the same for system memory buffers.

This change will also mitigates #2940
