Wanpeng Li 1ca8ec532f tick/nohz: Set the correct expiry when switching to nohz/lowres mode 
commit 0ff53d0964 sets the next tick interrupt to the last jiffies update,
i.e. in the past, because the forward operation is invoked before the set
operation. There is no resulting damage (yet), but we get an extra pointless
tick interrupt.

Revert the order so we get the next tick interrupt in the future.

Fixes: commit 0ff53d0964 "tick: sched: Force tick interrupt and get rid of softirq magic"
