Set NDP hop limit in accordance with RFC 4861
...and do not populate link address cache at dispatch. This partially
reverts 313c767b0001bf6271405f1b765b60a334d6e911, which caused malformed
packets (e.g. NDP Neighbor Adverts with incorrect hop limit values) to
populate the address cache. In particular, this masked a bug that was
introduced to the Neighbor Advert generation code in
7c1587e3401a010d1865df61dbaf117c77dd062e.
