Nikolay Aleksandrov 996ba2f0d7 bonding: fix xfrm state handling when clearing active slave 
[ Upstream commit c4c5c5d2ef ]

If the active slave is cleared manually the xfrm state is not flushed.
This leads to xfrm add/del imbalance and adding the same state multiple
times. For example when the device cannot handle anymore states we get:
 [ 1169.884811] bond0: (slave eni0np1): bond_ipsec_add_sa_all: failed to add SA
because it's filled with the same state after multiple active slave
clearings. This change also has a few nice side effects: user-space
gets a notification for the change, the old device gets its mac address
and promisc/mcast adjusted properly.

Fixes: 18cb261afd ("bonding: support hardware encryption offload to slaves")
