tools lib traceevent: Fix error path on pevent_parse_event
If __pevent_parse_format() succeeded but add_event() failed, 'ret' didn't have a proper error code. Set it to PEVENT_ERRNO__MEM_ALLOC_FAILED. In addition, at that point 'event' also has fields and format information and they all need to be freed. Call pevent_free_format() to handle it.
