perf probe: Clean up probe_point_lazy_walker() return value

Newer compilers (gcc 4.6) complains about:

        return ret < 0 ?: 0;

For the following reason:

  util/probe-finder.c: In function ‘probe_point_lazy_walker’:
  util/probe-finder.c:1331:18: error: the omitted middle operand in ?: will always be ‘true’, suggest explicit middle operand [-Werror=parentheses]

And indeed the return value is a somewhat obscure (but correct) value
of 'true', so return 'ret' instead - this is cleaner and unconfuses
GCC as well.
