[PATCH] perf: fix two warning in bench/numa

[Wei Yang <weiyang@linux.vnet.ibm.com>]

There two warnings in bench/numa, when buiding 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 ‘%lx’ expects argument of t'long unsigned int’, but argument 5 has type ‘u64’ [-Werror=format]

This patch fixs these two warnings.
