wireguard: netlink: avoid variable-sized memcpy on sockaddr
Doing a variable-sized memcpy is slower, and the compiler isn't smart
enough to turn this into a constant-size assignment.
Further, Kees' latest fortified memcpy will actually bark, because the
destination pointer is type sockaddr, not explicitly sockaddr_in or
sockaddr_in6, so it thinks there's an overflow:
memcpy: detected field-spanning write (size 28) of single field
"&endpoint.addr" at drivers/net/wireguard/netlink.c:446 (size 16)
Fix this by just assigning by using explicit casts for each checked
case.
