What would happen if there is no any non-local interface

if there is no non-local address, address.isLinkLocalAddress() would return false, This function wouldn't return directly, Continue with the logic below, same as if it was a lookback address.

@AlbumenJ Just suggesstion:add a parameter called "allowLinkLocal(boolean)" in some related method( i find two extend point from original structure) .And user can config the value in system config file while it's default value is true to prevent the situation that though there is no any non-local interface and it also work , it's ok?

Refer to https://github.com/apache/dubbo/pull/14793/files#r1814182854, address.isLinkLocalAddress() shouldn't affect if there is no non-local address. I don't have a Dubbo environment locally, Can you help test the changes? thanks a lot.
