extmod/network_nina: Fix the AP security mode constants.

The only AP security mode supported is actually WPA/WPA2 not WEP. The
firmware command `0x19` starts the AP using `WIFI_AUTH_WPA_WPA2_PSK`
mode.

There are no functional changes in this commit, it just fixes the constant
names and removes the useless sanity checks for WEP.
