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.
