IMPALA-3517: S3: Get rid of hdfsDelete() warning message

In the patch for IMPALA-3452, a bug was introduced which does an
unnecessary call to hdfsDelete() on the staging directory of a
partition(s), when the user selects the option of skipping the
staging step. Also, this delete will not happen when it should happen,
e.g on HDFS partitions. (Although it will be deleted by the
coordinator later).

This patch fixes this bug by making sure that we delete the staging
directory when it is necessary and skip the call to delete when we
do not want it.
