perf top: Fix annotate segv
Before we had sym_counter, it was initialized to zero and we used that
as an index in the global attrs variable, now we have a list of evsel
entries, and sym_counter became sym_evsel, that remained initialized to
zero (NULL): b00m.
Fix it by initializing it to the first entry in the evsel list.
