perf top: Fix crash when annotating symbol

Ravi reported crash in perf top --stdio when annotating a function [1].
The issue was, that we don't pass evsel pointer into symbol__annotate()
function, which got over looked in the last annotation changes.

Committer note:

This fixes the crash, but makes it stumble into another bug, double
locking the annotation data structures, that is in turn fixed by the
next patch in this series.
