fixed the missing class init status update for native clinits. Since we moved that to the clinit RETURN in r24, it has to be duplicated in NATIVERETURN for native clinits. Factoring out to DIRECTCALLRETURN is not an option since there is no good way to determine if the direct call included a clinit (we would have to look at the code, which is suboptimal performance- and change resilience-wise). Thanks to Franz Weitl for the report
