net,socket: introduce DECLARE_SOCKADDR helper to catch overflow at build time
proto_ops->getname implies copying protocol specific data into storage unit (particulary to __kernel_sockaddr_storage). So when we implement new protocol support we should keep such a detail in mind (which is easy to forget about). Lets introduce DECLARE_SOCKADDR helper which check if storage unit is not overfowed at build time. Eventually inet_getname is switched to use DECLARE_SOCKADDR (to show example of usage).
