[PATCH] perf: probe: avoid segfault if passed with ''.

Since parse_perf_probe_point() deals with a user passed argument, we should not assume it to be a valid string. Without this patch, if pass '' to perf probe, a segfault raises: $ perf probe -a '' Segmentation fault This patch checks argument of parse_perf_probe_point() before string processing
