[SPARK-13490][ML] ML LinearRegression should cache standardization param value
## What changes were proposed in this pull request?
Like #11027 for ```LogisticRegression```, ```LinearRegression``` with L1 regularization should also cache the value of the ```standardization``` rather than re-fetching it from the ```ParamMap``` for every OWLQN iteration.
cc srowen
## How was this patch tested?
No extra tests are added. It should pass all existing tests.
