bonding: fix send_peer_notif overflow
Bonding send_peer_notif was defined as u8. Since commit 07a4ddec3ce9
("bonding: add an option to specify a delay between peer notifications").
the bond->send_peer_notif will be num_peer_notif multiplied by
peer_notif_delay, which is u8 * u32. This would cause the send_peer_notif
overflow easily. e.g.
ip link add bond0 type bond mode 1 miimon 100 num_grat_arp 30 peer_notify_delay 1000
To fix the overflow, let's set the send_peer_notif to u32 and limit
peer_notif_delay to 300s.
