vxlan: Add missing entries to vxlan_get_size()

Browse Source 
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.

Fixes: 3511494ce2 ("vxlan: Group Policy extension")
Fixes: e1e5314de0 ("vxlan: implement GPE")
Fixes: 0ace2ca89c ("vxlan: Use checksum partial with remote checksum offload")
Fixes: f9c4bb0b24 ("vxlan: vni filtering support on collect metadata device")
