[PATCHv8 21/26] v4l: vb2-dma-contig: add reference counting for a device from allocator context

This patch adds taking reference to the device for MMAP buffers. Such buffers, may be exported using DMABUF mechanism. If the driver that created a queue is unloaded then the queue is released, the device might be released too. However, buffers cannot be released if they are referenced by DMABUF
