[SPARK-19599][SS]Clean up HDFSMetadataLog for Hadoop 2.6+
## What changes were proposed in this pull request?
SPARK-19464 removed support for Hadoop 2.5 and earlier, so we can do some
cleanup for HDFSMetadataLog.
This PR includes the following changes:
- Remove the workaround codes for HADOOP-10622.
- Remove unnecessary `writer: (T, OutputStream) => Unit` and just call
`serialize` directly.
## How was this patch tested?
Jenkins
