Fix a problem when CARP is enabled on the interface for IPv4
but not for IPv6.  The current checks in nd6_nbr.c along with the
old version will result in ifa being NULL and subsequently the
packet will be dropped.  This prevented NS/NA, from working and
with that IPv6.

Now return the ifa from the carp lookup function in two cases:
1) if the address matches, is a carp address, and we are MASTER
   (as before),
2) if the address matches but it is not a carp address at all (new).
