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).
