va: postproc: Use allocation caps when creating sink pool.

Browse source 
When an input buffer needs to be copied into a VA memory, it's
required to create a buffer pool. This patch uses the
propose_allocation() caps to instantiate the allocator and pool,
instead of the negotiated caps, which rather represents the resolution
to display.
