lockup_detector: Sync touch_*_watchdog back to old semantics
During my rewrite, the semantics of touch_nmi_watchdog and
touch_softlockup_watchdog changed enough to break some drivers
(mostly over preemptable regions).
These are cases where long delays on one CPU (due to
print_delay for example) can cause long delays on other
CPUs - so we must 'touch' the nmi_watchdog flag of those
other CPUs as well.
This change brings those touch_*_watchdog() functions back in line
with to how they used to work.
