vxlan: Add missing entries to vxlan_get_size()
[ Upstream commit 4e4b1798cc90e376b8b61d0098b4093898a32227 ]
There are some attributes added by vxlan_fill_info() which are not
accounted for in vxlan_get_size(). Add them.
I didn't find a way to trigger an actual problem from this miscalculation
since there is usually extra space in netlink size calculations like
if_nlmsg_size(); but maybe I just didn't search long enough.
