This function will take an array of DMABuf GstMemory and an array of fd, and create a VASurfaceID with those fds. Later that VASurfaceID is attached to each DMABuf through GstVaBufferSurface. In order to free the surface GstVaBufferSurface now have GstVaDisplay member, and _buffer_surface_unref() were added.
