esp_netif: Post IP event for PPP netifs unconditionally

Browse Source 
IP update notification for "point to point" interfaces is performed
via the same callback function as for any other interfaces (dhcp_cb,
although it's not DHCP related). In P2P interfaces we have to assure
that we always get a notification, so we can set the interface up.
This was omitted when getting the same IP address for the second
time, causing the PPPoS interface (in esp-modem applications) failing
to reconnect if disconnected.
