wwan: core: require WWAN netdev setup callback existence

The setup callback will be unconditionally passed to the
alloc_netdev_mqs(), where the NULL pointer dereference will cause the
kernel panic. So refuse to register WWAN netdev ops with warning
generation if the setup callback is not provided.
