dma-buf: DMABUF_DEBUG should depend on DMA_SHARED_BUFFER
[ Upstream commit cca62758ebdd71fcfb6d589d6487a7f26398d50d ]
DMA-BUF debug checks are an option of DMA-BUF. Enabling DMABUF_DEBUG
without DMA_SHARED_BUFFER does not have any impact, as drivers/dma-buf/
is not entered during the build when DMA_SHARED_BUFFER is disabled.
