[PATCH] dma-contiguous: remove debug code to removed CONFIG_CMA_DEBUG

[Lukas Bulwahn <lukas.bulwahn@xxxxxxxxx>]

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.
