Subject: [PATCH AUTOSEL 4.4 14/29] net: bonding: debug: avoid printing debug logs when bond is not notifying peers

[ Upstream commit fee32de284ac277ba434a2d59f8ce46528ff3946 ]
Currently "bond_should_notify_peers: slave ..." messages are printed whenever

Print logs only when the peer notification happens.
