When an area-range command is applied in an ABR, the more specific prefixes
need to be removed.

IPV6_HDRINCL later, so the kernel will handle it, but for the time being
let's just stop trying to use the IPv4 code for IPv6.)

Currently the PIM6d component is getting displayed under
"show ip prefix-list" instead of "show ipv6 prefix-list".
Fixed it.

When a client disconnects, we need to check & remove NHT entries for
other SAFIs too. Otherwise we crash later trying to access stale data.
