Fix perf probe to probe an inlne function which has no entry pc or low pc but only has ranges attribute. This seems very rare case, but I could find a few examples, as same as probe_point_search_cb(), use die_entrypc() to get the entry address in probe_point_inline_cb() too. Without this patch: # perf probe -D __amd_put_nb_event_constraints Failed to get entry address of __amd_put_nb_event_constraints. Probe point '__amd_put_nb_event_constraints' not found. Error: Failed to add events. With this patch: # perf probe -D __amd_put_nb_event_constraints p:probe/__amd_put_nb_event_constraints amd_put_event_constraints+43 Committer testing: Before: [root@quaco ~]# perf probe -D __amd_put_nb_event_constraints Failed to get entry address of __amd_put_nb_event_constraints. Probe point '__amd_put_nb_event_constraints' not found. Error: Failed to add events.
