Namhyung Kim bd62de0808 perf annotate-data: Do not retry for invalid types ...

In some cases, it was able to find a type or location info (for per-cpu
variable) but cannot match because of invalid offset or missing global
information.  In those cases, it's meaningless to go to the outer scope
and retry because there will be no additional information.

Let's change the return type of find_matching_type() and bail out if it
returns -1 for the cases.
