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

Thank you for the fix. Applied to linux-kselftest fixes branch for Linux 5.19-rc3 or rc4
