> HBASE-8300 tried to fix this issue by adding 'StoreFile#closeReader()' call.  However,
after the open reader calls, there are 4 'return null' calls before the close call.  When
I run TestSplitTransaction#testWholesomeSplit(), 2 of the 'return null' calls were hit multiple
times (which means the opened file is not closed).  
> The fix needs to make sure that StoreFile#closeReader() is called in all situation.
