James Tucker 7df6f8736a wgengine/netstack: only add addresses to correct protocols
Prior to an earlier netstack bump this code used a string conversion
path to cover multiple cases of behavior seemingly checking for
unspecified addresses, adding unspecified addresses to v6. The behavior
is now crashy in netstack, as it is enforcing address length in various
areas of the API, one in particular being address removal.

As netstack is now protocol specific, we must not create invalid
protocol addresses - an address is v4 or v6, and the address value
contained inside must match. If a control path attempts to do something
otherwise it is now logged and skipped rather than incorrect addressing
being added.

Fixes tailscale/corp#15377
