[ML] Close sample stream in post_data endpoint (#43235) 

A static code analysis revealed that we are not closing
the input stream in the post_data endpoint.  This
actually makes no difference in practice, as the
particular InputStream implementation in this case is
org.elasticsearch.common.bytes.BytesReferenceStreamInput
and its close() method is a no-op. However, it is good
practice to close the stream anyway.
