clocksource: Print clocksource name when clocksource is tested unstable

Browse source

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".
