In hists browser, press hotkey 'a' to annotate current symbol. Now it causes segment fault if 'a' is pressed on a null symbol. Here are 2 small bugs: - In perf_evsel__hists_browse, the condition check after 'a' is pressed is not correct, we should check ->sym instead of ->map. - In symbol__tui_annotate we must check whether sym is NULL or not before getting annotation structure. This patch fixes above 2 small bugs.
