fix the softlockup watchdog to actually work
this Xen related commit:
commit 966812dc98e6a7fcdf759cbfa0efab77500a8868

Ignore stolen time in the softlockup watchdog
broke the softlockup watchdog to never report any lockups. (!)
print_timestamp defaults to 0, this makes the following condition
always true:
if (print_timestamp < (touch_timestamp + 1) ||
and we'll in essence never report soft lockups.
apparently the functionality of the soft lockup watchdog was never
actually tested with that patch applied ...
