New space quota policy doesn't take effect if quota policy is changed after violation

Steps to reproduce

 1: set_quota TYPE => SPACE, TABLE => 'test25', LIMIT => '2M', POLICY => NO_WRITES

2: ./hbase pe --table="test25" --nomapred --rows=300  sequentialWrite  10

3: Observe that after some time data usage is 3 mb and policy is in violation

4: now try to insert some data again in the table and observe that operation fails due to NoWritesViolationPolicyEnforcement 

5: Now change the quota policy 

 set_quota TYPE => SPACE, TABLE => 'test25', LIMIT => '2M', POLICY => NO_WRITES_COMPACTIONS

6: Now again try to insert data once new policy takes effect

7: Observe that still operation fails but because of old policy and not new policy.
