net: bonding: move bond_should_notify_peers, e.g. into rtnl lock block

This patch tries to avoid the possible peer notify event loss.

In bond_mii_monitor()/bond_activebackup_arp_mon(), when we hold the rtnl lock:
- check send_peer_notif again to avoid unconditionally reducing this value.
- send_peer_notif may have been reset. Therefore, it is necessary to check
  whether to send peer notify via bond_should_notify_peers() to avoid the
  loss of notification events.
