This patch converts wireguard from using legacy struct genl_ops to struct genl_split_ops, by applying the same transformation as genl_cmd_full_to_split() does. WGDEVICE_A_MAX is swapped for WGDEVICE_A_PEERS, which is currently equivalent and is what ynl-gen would generate. This is an incremental step towards adopting netlink policy code generated by ynl-gen. This is a trivial patch with no behavioural changes intended.
