bonding: fix length of actor system

commit 414dd6fb9a1a1b59983aea7bf0f79f0085ecc5b8 upstream.

The attribute IFLA_BOND_AD_ACTOR_SYSTEM is sent to user space having the
length of sizeof(bond->params.ad_actor_system) which is 8 byte. This
patch aligns the length to ETH_ALEN to have the same MAC address exposed
as using sysfs.
