watchdog: use suspend/resume interface in fixup_ht_bug()

watchdog: use suspend/resume interface in fixup_ht_bug()

Remove watchdog_nmi_disable_all() and watchdog_nmi_enable_all() since
these functions are no longer needed.  If a subsystem has a need to
deactivate the watchdog temporarily, it should utilize the
watchdog_suspend() and watchdog_resume() functions.
