perf report: Use ui__warning in some more places
Arnaldo Carvalho de Melo [Wed, 3 Aug 2011 15:33:24 +0000 (12:33 -0300)]
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.
