perf bench: Clean up bench/bench.h
...
Clean up initializers in bench.h:
- No need to break the line for function prototypes, they are more
readable in a single line. (even if checkpatch complains about it
- We try to align definitions / structure fields vertically,
to make it all a bit more readable.
