igb: fix i211 support

igb_ethdev.c contains function eth_igb_infos_get() which should set
number of tx/rx queues supported by the hardware. It contains huge
[switch] but there is no i211 case!
Also, there are few other places which mention i210, but not mention i211.

I didn't check it enough to say it is totally correct.
For now I see that it just able to send and receive some packets.
