reactos/dll/win32/iphlpapi/ipstats_reactos.c
Joachim Henze a5360f542f [IPHLPAPI] Formatting only, no functional change 
- Strip inconsistent spaces from the spec file.
- iphlpapi_main: Harmonize inconsistent and line-wasting function-comments and fix mixed space-tab-indentation.
- ipstats_reactos.c: Compactify horizontally accordingly to the coding guidelines

I am interested in that code for a backport, so I want it to be well-formatted.
Ftr: IPHLPAPI was *forked* more than a decade ago from Wine.
Therefore no diff ever was guarded within those files whenever we implemented anything here.
