Merge #14728: fix uninitialized read when stringifying an addrLocal
b7b36decaf878a8c1dcfdb4a27196c730043474b fix uninitialized read when stringifying an addrLocal (Kaz Wesley)

Pull request description:
Reachable from either place where SetIP is used when all of:
- our best-guess addrLocal for a peer is IPv4
- the peer tells us it's reaching us at an IPv6 address
- NET logging is enabled
In that case, SetIP turns an IPv4 address into an IPv6 address without
setting the scopeId, which is subsequently read in GetSockAddr during
CNetAddr::ToStringIP and passed to getnameinfo. Fix by ensuring every
constructor initializes the scopeId field with something.
