Title: Fix report_note fail @ L77 when vendor MAC is not in OUI list

arp_sweep fails to report a host when OUI_LIST::lookup_oui_company_name fails to find the MAC address' vendor name. Resolves by setting company variable to 'Vendor Unknown' if the lookup fails.

Is there any sense in logging these failures to add things to the OUI_LIST?
