bonding: fix active-backup transition after link failure
After the recent fix in commit 1899bb325149 ("bonding: fix state
transition issue in link monitoring"), the active-backup mode with
miimon initially come-up fine but after a link-failure, both members
transition into backup state.
Following steps to reproduce the scenario (eth1 and eth2 are the
slaves of the bond):
ip link set eth1 up
ip link set eth2 down
sleep 1
ip link set eth2 up
ip link set eth1 down
cat /sys/class/net/eth1/bonding_slave/state
cat /sys/class/net/eth2/bonding_slave/state
Fixes: 1899bb325149 ("bonding: fix state transition issue in link monitoring")
