Your Class BnkMIS needs to implement a Constructor with a StandardController parameter as documented here:

public BnkMIS(ApexPages.StandardController stdController) {
    //Bank_MIS__c mis = (Bank_MIS__c) stdController.getRecord();
}

If you need a StandardSetController instead, you need to change it in your Test as describe in the StandardSetController documentation:

List<Bank_MIS__c> records = new List<Bank_MIS__c>{ bm };
ApexPages.StandardSetController ssc = new ApexPages.StandardSetController(records);
