ALSA: compress_offload: import DMA_BUF namespace

The compression offload code cannot be in a loadable module unless it
imports that namespace:

ERROR: modpost: module snd-compress uses symbol dma_buf_get from namespace DMA_BUF, but does not import it.
ERROR: modpost: module snd-compress uses symbol dma_buf_put from namespace DMA_BUF, but does not import it.
ERROR: modpost: module snd-compress uses symbol dma_buf_fd from namespace DMA_BUF, but does not import it.
