pppos client: modem netif fix ignoring potential modem-start error

Browse Source 
esp-modem netif glue layer implements esp-netif attach callback to setup corresponding driver functions and start the modem. The error code of esp_modem_start_ppp() was ignored and ESP_OK returned in all cases. Fixed by passing esp_modem_start_ppp()'s error code to post_attach callback.

Closes https://github.com/espressif/esp-idf/issues/5430
