Subject: [PATCH] perf: fix use_browser infinite loop bug in annotate

This patch fixes an infinite loop problem with perf annotate when
the TUI is not used. When the perfconfig file is not found use_browser
remains at -1, when found and tui is disabled use_browser = 0. Thus the
correct test for TUI is use_browser > 0.
