Commit acc2f3e42d4a ("mm/cma: drop CONFIG_CMA_DEBUG") removes the config
CMA_DEBUG and the debug code in cma.c, but misses debug code in
kernel/dma/contiguous.c.

Remove this dead code from this removed config option.

Christoph, please drop this patch in your for-next branch if possible.

Andrew has picked this patch already and squashed it together with the
commit "mm/cma: drop CONFIG_CMA_DEBUG" in the mm tree. So, you do not
need to add it anymore.
