currently in hab driver, it want to hold all bufs as dmabuf for fulture implement,
and it's hard to get dmabuf fd/handle from a kva, so hab need to generate a new
dmabuf for itself, and this will intruduce audio crash issue
in conclusion, for now hab just accept dma fd/handl as input in KHAB export path.
