console_cmd_ifconfig: not supporting the ppp netif and will panic (IDFGH-11607)

[dapeng0512]

Answers checklist.

• I have read the documentation for esp-protocols components and the issue is not addressed there.
• I have updated my esp-protocols branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

When i enable ppp with 4g module, run ifconfig will panic. I found panic's place.

version: 1.0.0

static void print_iface_details(esp_netif_t *esp_netif)
{
    ...

    struct netif *lwip_netif = esp_netif_get_netif_impl(esp_netif); // !!! return NULL

    ESP_LOGI(TAG, "Interface Number: %d", lwip_netif->num);  // PANIC at here

    ...

    ESP_LOGI(TAG, "Link Status: %s\n", netif_is_link_up(lwip_netif) ? "UP" : "DOWN"); // Here will also lead to panic

}

If it’s simply not going to let it panic, the ppp netif doesn’t support, that feels a big flaw!!!

@dapeng0512, thank you for bringing this issue to our attention. This component has not been tested on the PPP interface yet. I will address and fix it in the upcoming release soon.
