[FLINK-7979][minor] Use Log.*(Object, Throwable) overload to log exceptions
## What is the purpose of the change
When logging an exception, we often convert the exception to string or call
`.getMessage()`. Instead we can use the log method overloads which take
`Throwable` as a parameter.
## Brief change log
- *Remove unnecessary `e.getMessage()`, logging exception use
LOG.\*(Object, Throwable)*
