[nrf noup] Increase the maximum number of prefixes to match

the maximum number of IPv6 addresses per interface. Zephyr ipv6_nbr implementation requires the given address to have a matching prefix set on the interface. Otherwise, the default router is used for sending neighbor advertisement and as a result, in case there are multiple routers in the network, the packet can be sent to the invalid interface (not the one which issued neighbor solicitation).
