bridge: netlink: account for the IFLA_BRPORT_PROXYARP_WIFI attribute size and policy

[ Upstream commit 786c2077ec8e9eab37a88fc14aac4309a8061e18 ]

The attribute size wasn't accounted for in the get_slave_size() callback
(br_port_get_slave_size) when it was introduced, so fix it now. Also add
a policy entry for it in br_port_policy.
