[CARBONDATA-3756] Fix stage query bug it only read the first blocklet of
each carbondata file
Why is this PR needed?
The query of stage files only read the first blocklet of each carbondata
file.
So when the file contains multiple blocklets, the query result will be
wrong.
What changes were proposed in this PR?
The query of stage files should read the all blocklets of all carbondata
files.
Does this PR introduce any user interface change?
No
Is any new testcase added?
No
This closes #3684
