perf report: Use the right symbol for annotation

In non symbolic views, i.e. --sort without "symbol", as in:

 perf report --sort comm

We're segfaulting in the --tui because we're testing the symbol resolved
and then trying to use the symbol on the histogram entry where we're
coalescing all hits for a COMM, and the first hist_entry for a comm may
have a NULL symbol, i.e. the RIP didn't resolve to any symbol.

In this case we're segfaulting, fix it by testing against the symbol in
the histogram entry.
