[SPARK-22799][ML] Bucketizer should throw exception if single- and
multi-column params are both set
## What changes were proposed in this pull request?
Currently there is a mixed situation when both single- and multi-column are
supported. In some cases exceptions are thrown, in others only a warning log is
emitted. In this discussion
https://issues.apache.org/jira/browse/SPARK-8418?focusedCommentId=16275049&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16275049,
the decision was to throw an exception.
The PR throws an exception in `Bucketizer`, instead of logging a warning.
## How was this patch tested?
