When using `iotop` utility, in columns "SWAPIN" and "IO" is shows `?unavailable?`. At the bottom it says `CONFIG_TASK_DELAY_ACCT not enabled in kernel, cannot determine SWAPIN and IO %`.

This is a regression compared to previous major version linux-zen 5.13.x

Additional info:
* package version(s) 5.14.9-zen2-1-zen

Steps to reproduce:

1. Run `sudo iotop`.

## Expected

There's no columns with "unavailable" entries

## Actual

IO and SWAPIN columns has entry "unavailable".
This task depends upon

I can confirm, even though the kernel config does imply the feature is available:

$ zgrep DELAY_ACCT /proc/config.gz
