[CARBONDATA-1490] Fixed memory allocation for carbon row
Analysis: While creating carbon row the space for measures is assigned
based on outputLength and not on measureCount which will tend to allocate more
space than is actually needed.
**outputLength = measureCount + ((noDictCount + complexCount) > 0 ? 1 : 0)
+ 1**
When the table has 1 complex column then measureCount=0, noDictCount=0,
complexCount=1
therefore, outputLength = 2
Even if there are no measure columns the measure object is created with 2
null values.
Solution: Create measure object based on the measureCount.
