ppp: Fix null pointer dereference on registration failure

Browse source

register_netdevice() will call the device's ndo_uninit operation if
registration fails after it calls the ndo_init operation.  However
ppp_dev_uninit() uses ppp->ppp_net which is currently not set until
after register_netdevice() returns.

This was fixed upstream as part of commit 96d934c70d "ppp: add
rtnetlink device creation support".
