[PATCH net-next 2/3] wireguard: peer: Replace sockaddr with sockaddr_inet

[Kees Cook <kees@kernel.org>]

As part of the removal of the variably-sized sockaddr for kernel
internals, replace struct sockaddr with sockaddr_inet in the endpoint
union.

No binary changes; the union size remains unchanged due to sockaddr_inet
matching the size of sockaddr_in6.
