perf bench: Fix two warnings
There are two warnings in bench/numa, when building this on 32-bit
machine.
The warning output is attached:
bench/numa.c:1113:20: error: comparison between signed and unsigned integer expressions [-Werror=sign-compare]
bench/numa.c:1161:6: error: format â%lxâ expects argument of t'long unsigned intâ, but argument 5 has type âu64â [-Werror=format]
This patch fixes these two warnings.
