Prarit Bhargava requested to merge prarit/centos-stream-9:RHEL-19589 into main

JIRA: https://issues.redhat.com/browse/RHEL-19589

clocksource: Print clocksource name when clocksource is tested unstable  

Some "TSC fall back to HPET" messages appear on systems having more than  
2 NUMA nodes:  

clocksource: timekeeping watchdog on CPU168: hpet read-back delay of 4296200ns, attempt 4, marking unstable  

The "hpet" here is misleading the clocksource watchdog is really  
doing repeated reads of "hpet" in order to check for unrelated delays.  
Therefore, print the name of the clocksource under test, prefixed by  
"wd-" and suffixed by "-wd", for example, "wd-tsc-wd".
