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.
