vaapipostproc: fix "mixed" mode deinterlacing.

Browse source 
In "mixed" interlaced streams, the buffer contains additional flags that
specify whether the frame contained herein is interlaced or not. This means
that we can alternatively get progressive or interlaced frames. Make sure
to disable deinterlacing at the VPP level when the source buffer is no longer
interlaced.
