wireless module - dont segv e if connman daemon restarts

so i get a new service of type WIRELESS_SERVICE_TYPE_NONE that's going
to suck when accessing arrays by type like wireless does like
array[cs->type] ... so check type value and if its invalid kill off
the cs as we can't do much useful with it. this fixes an actual segv e
gets if you restart the connamn daemon while e runs.
