I think reverting this is the correct solution for 3.0 and 3.x. Changing
defaults in minors while in this case is probably fine, it's not good practice.
Backporting CASSANDRA-13521 completely is also a bit questionable.
The original problem from CASSANDRA-13797 of the interrupted exceptions is only
very minor, and likely not possible outside of CCM clusters.

> Fix unbounded validation compactions on repair
> ----------------------------------------------
>
> Key: CASSANDRA-14332
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14332
> Project: Cassandra
> Issue Type: Bug
> Reporter: Kurt Greaves
> Priority: Major
>
> After CASSANDRA-13797 it's possible to cause unbounded, simultaneous
> validation compactions as we no longer wait for validations to finish.
> Potential fix is to have a sane default for the # of concurrent validation
> compactions by backporting CASSANDRA-13521 and setting a sane default.
