dma-mapping: fix dma_common_get_sgtable() conditional compilation

Hi Greg,

Are you maintaining drivers/base/dma-mapping.c? The enclosed path is needed to enable DMABUF handling on V4L2 on some architectures, like x86_64, as we need dma_common_get_sgtable() on drivers/media/v4l2-core/videobuf2-dma-contig.c.

Would you mind acking it, in order to let this patch flow via my tree? This way, I can revert a workaround I had to apply there, in order to avoid linux-next compilation breakage.

Thanks!
Mauro

dma_common_get_sgtable() function doesn't depend on ARCH_HAS_DMA_DECLARE_COHERENT_MEMORY, so it must not be compiled conditionally.
