netif_napi_add() could report an error like this below due to it allows
to pass a format string for wildcarding before calling
dev_get_valid_name(),
"netif_napi_add() called with weight 256 on device eth%d"
For example, hns_enet_drv module does this.
hns_nic_try_get_ae
hns_nic_init_ring_data
netif_napi_add
register_netdev
dev_get_valid_name
Hence, make it a bit more human-readable.
