8309959: JFR: Display N/A for missing data amount

[egahlin]

Could I have a review of a follow up fix to JDK-8309550.

Testing: jdk/jdk/jfr

Plan is to clean up the formatting of missing values after, or during, refactoring of ValueFormatter, but this will done as an enhancement as it involves larger code changes.

Thanks
Erik
