amt: fix size calculation in amt_get_size()
amt_get_size() incorrectly used sizeof(struct iphdr) for the sizes of
IFLA_AMT_DISCOVERY_IP, IFLA_AMT_REMOTE_IP, and IFLA_AMT_LOCAL_IP.
These attributes contain IPv4 addresses (__be32), not full IP headers.
Replace sizeof(struct iphdr) with sizeof(__be32) to avoid over-allocating
netlink message space.
Fixes: b9022b53adad ("amt: add control plane of amt interface")
