Description

From UT report of HBASE-15120 against branch-1.1, we could see below failure:

testIncrementWithReturnResultsSetToFalse(org.apache.hadoop.hbase.regionserver.wal.TestDurability)  Time elapsed: 0.111 sec  <<< FAILURE!
java.lang.AssertionError: expected null, but was:<keyvalues={row1/family:col1/1452864457248/Put/vlen=8/seqid=4}>
	at org.junit.Assert.fail(Assert.java:88)
	at org.junit.Assert.failNotNull(Assert.java:755)
	at org.junit.Assert.assertNull(Assert.java:737)
	at org.junit.Assert.assertNull(Assert.java:747)
	at org.apache.hadoop.hbase.regionserver.wal.TestDurability.testIncrementWithReturnResultsSetToFalse(TestDurability.java:215)

Checking the history, this should be a regression caused by HBASE-15031, and confirmed the UT could pass before commit c5cfea4e37a.

Reason of the failure is isReturnResult=false on slow path (HRegion#slowButConsistentIncrement) is not respected
