ip-neighbor: do not use sas to determine NS source address
Using the source address selection algorithm to determine the best source
of an NS for address resolution risks incompatible behavior.
It may choose a source address that is off-link to the other host.
Which may drop it.
A safer approach is to always use the link-local address as the SA.
It's recommended to pick a source that an application will later use,
as VPP is mostly a router, that rarely applies. And regardlessly we have
no mechanism to signal from an application that triggered address resolutiuon
what source address it intends to use.
Type: fix
