Subject: [PATCH perf 2/4] perf top: Fix behaviour of Shift-Tab in annotated
 view with nothing focussed

gcc 6 catches a case of missing braces:

ui/browsers/annotate.c: In function 'annotate_browser__run':
ui/browsers/annotate.c:760:5: error: statement is indented as if it were guarded by... [-Werror=misleading-indentation]
     if (nd == NULL)
     ^~

ui/browsers/annotate.c:758:4: note: ...this 'if' clause, but it is not
    if (nd != NULL)
    ^~

Fixes: c97cf42219b7 ("perf top: Live TUI Annotation")
