c3a234fe99 ipv6: Fix source address with many addresses in same network
Previously ipv6 multi-address support decided packet source
address based on its destination. This doesn't work if NuttX
device has multiple addresses within same subnet.

Instead when a packet is a response to existing connection,
the source address should be based on the destination address
used in the received packet.

4c99ad1ba9 net/utils: Switch argument order of net_ipv6_pref2mask
When implementing IPv6-related logic, we found the `net_ipv6_pref2mask`
and `net_ipv6addr_copy` are using different argument order:
```
net_ipv6addr_copy(ifaddr->addr, addr);
net_ipv6_pref2mask(preflen, ifaddr->mask);
```
Change the order to:
```
net_ipv6addr_copy(ifaddr->addr, addr);
net_ipv6_pref2mask(ifaddr->mask, preflen);
```

96233e0c42 net/netdev: Support multiple IPv6 addresses per device
Compatible with previous usage, because may network drivers are using old member name to print logs, and there's no significant need to change them now.
