It depends on when the message was sent. If it was sent during a
previous peering, it is ignored before it reaches the state machine by
checking pg->old_peering_msg in OSD::handle_pg_log.

Otherwise, if the log was sent after the current peering attempt
started, the primary does enter the Crashed state. It's a bug that a log
was received in this case, since GetInfo is the first stage of peering,
and no logs were requested yet.
