Make a code path easier for static analyzers to understand

Browse Source 
prev cannot be NULL here in the hostapd_eid_country_add() call since
prev is set whenever start becomes non-NULL. That seems to be a bit too
difficult for some static analyzers, so check the prev pointer
explicitly to avoid false warnings.
