nohz: Get timekeeping max deferment outside jiffies_lock
We don't need to fetch the timekeeping max deferment under the
jiffies_lock seqlock.
If the clocksource is updated concurrently while we stop the tick,
stop machine is called and the tick will be reevaluated again along with
uptodate jiffies and its related values.
