[SPARK-15664][MLLIB] Replace FileSystem.get(conf) with path.getFileSystem(conf) when removing CheckpointFile in MLlib
## What changes were proposed in this pull request?
if sparkContext.set CheckpointDir to another Dir that is not default FileSystem, it will throw exception when removing CheckpointFile in MLlib.
So we should always get the FileSystem from Path to avoid wrong FS problem.
## How was this patch tested?
N/A
