[BUGFIX PATCH V2 3/6] perf/probe: Fix to probe an inline function which has no entry pc

[Masami Hiramatsu]

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 _text+34059
