[ Upstream commit 12a29115be72dfc72372af9ded4bc4ae7113a729 ]

When building selftests/dma:
$ make -C tools/testing/selftests TARGETS=dma
I hit the following compilation error:

dma_map_benchmark.c:13:10: fatal error: linux/map_benchmark.h: No such file or directory
#include <linux/map_benchmark.h>
^~~~~~~~~~~~~~~~~~~~~~~

dma/Makefile does not include the map_benchmark.h path, so add
more including path, and fix include order in dma_map_benchmark.c

Fixes: 8ddde07a3d28 ("dma-mapping: benchmark: extract a common header file for map_benchmark definition")
