      for (contact con: conlist){
           Ids.put(con.accountId, con.Id);
      } 


      for(Account acc: [Select Id, vlocity_cmt__PersonContactId__c, Type from Account where Id In:Ids.keyset()]){      
                Account acnt = new Account();
                acnt.Id = acc.Id;
                acnt.status  = 'Inactive';
                AccList.add(acnt);
        }

    if(AccList.size()>0){  
        try{     
            update AccList;
        }
        catch(dmlexception e){
            conlist[0].adderror(e.getMessage()); 
        }

    }   
}

For this I suggest you to use Database class, using that you first get the error message and then append it to the record.

Database.SaveResult[] srList = Database.insert(AccList, false);
Integer count = 0;
// Iterate through each returned result
for (Database.SaveResult sr : srList) {
    if (!sr.isSuccess()) {
        // Operation failed, so get all errors                
        for(Database.Error err : sr.getErrors()) {
            System.debug('The following error has occurred.');                    
            System.debug(err.getStatusCode() + ': ' + err.getMessage());
            System.debug('Fields that affected this error: ' + err.getFields());

            AccList[count ].adderror(err.getMessage()); 
        }
    }
     count ++;
}
