https://github.com/apache/carbondata/pull/2892 [CARBONDATA-3069][Compaction] Fix bugs in setting cores for compaction
Current implementation for setting cores for compaction is wrong. It
will set the cores first and then set the flow to compaction, which
causes that the number set is always from 'loading.cores' instead of
'compaction.cores'.
In this commit, we fix this bug by setting the cores again when the user
changes the flow to compaction.

`No, it only affects the intermediate procedure`
- How it is tested? Please attach test report.
`Tested and verified in local machine`
- Is it a performance related change? Please attach the performance test report.
`For users whose 'compaction.cores' is not equal to 'loading.cores', the performance of compaction may change`
