Feng Tang 1500b93b61 perf symbols: Filter samples with unresolved symbol when "--symbols" option is used 
Report/top commands support to only handle specific symbols with
"--symbols" option, but current code will keep those samples whose
symbol can't be resolved, which should actually be filtered.

If we run following commands:
$perf record -a tree
$perf report --symbols intel_idle -n
the output will be:
