[Spark-7983] [MLlib] add require for one-based in loadLIBSVM
jira: https://issues.apache.org/jira/browse/SPARK-7983
Customers frequently use zero-based indices in their LIBSVM files. No
warnings or errors from Spark will be reported during their computation
afterwards, and usually it will lead to wired result for many algorithms (like
GBDT).
