…failure ## What changes were proposed in this pull request? We need to use `requiredSchema` in `LibSVMRelation` to project the fetch required columns when loading data from this data source. Otherwise, when users try to select `features` column, it will cause failure. ## How was this patch tested? `LibSVMRelationSuite`. Author: Liang-Chi Hsieh <simonh@tw.ibm.com> Closes #12986 from viirya/fix-libsvmrelation. (cherry picked from commit 635ef40) Signed-off-by: Cheng Lian <lian@databricks.com>
