Lars Hofhansl updated HBASE-14315:
----------------------------------
    Description: 
Another one of my micro optimizations.
In StoreScanner.next(...) we can actually save a call to KeyValueHeap.peek, which in my runs
of scan heavy loads shows up at top.

Based on the run and data this can safe between 3 and 10% of runtime.
