bonding: fix value exported by Netlink for peer_notif_delay

mainline inclusion
from mainline-v5.5-rc5
commit ee4f56f4
category: bugfix
bugzilla: 46933
CVE: NA

-------------------

IFLA_BOND_PEER_NOTIF_DELAY was set to the value of downdelay instead
of peer_notif_delay. After this change, the correct value is exported.
