Subject: [PATCH V3 15/15] rtla: Tools main loop cleanup

I probably started using "do {} while();", but changed all but osnoise_top
to "while(){};" leaving the ; behind.

Cleanup the main loop code, making all tools use "while() {}"

Changcheng Deng reported this problem, as reported by coccicheck:

Fix the following coccicheck review:
./tools/tracing/rtla/src/timerlat_hist.c: 800: 2-3: Unneeded semicolon
./tools/tracing/rtla/src/osnoise_hist.c:  776: 2-3: Unneeded semicolon
./tools/tracing/rtla/src/timerlat_top.c:  596: 2-3: Unneeded semicolon
