[SPARK-19991][CORE][YARN] FileSegmentManagedBuffer performance improvement
## What changes were proposed in this pull request?
Avoid `NoSuchElementException` every time `ConfigProvider.get(val, default)` falls back to default. This apparently causes non-trivial overhead in at least one path, and can easily be avoided.
See https://github.com/apache/spark/pull/17329
## How was this patch tested?
Existing tests
