perf report: Use ui__warning in some more places
So that we get a proper warning in the TUI in cases like: $ perf report --stdio -g fractal,0.5,caller --sort pid Selected -g but no callchain data. Did you call 'perf record' without -g? $ The --stdio case is ok because it uses fprintf, ui__warning is needed to figure out if --stdio or --tui is being used.
