netlink: Correctly calculate attribute length for address messages
In nl_addr_get() and nl_addr_dup() we step the attributes attached to each
RTM_NEWADDR message with a loop initialised with IFA_RTA() and
RTM_PAYLOAD() macros. RTM_PAYLOAD(), however is for RTM_NEWROUTE messages
(struct rtmsg), not RTM_NEWADDR messages (struct ifaddrmsg). Consequently
it miscalculates the size and means we can skip some attributes. Switch
to IFA_PAYLOAD() which we should be using here.
