timer: Fix hotplug regression
The recent timer wheel rework removed the get/put_cpu_var() pair in
the hotplug migration code, which results in:
BUG: using smp_processor_id() in preemptible [00000000] code: hib.sh/2845
...
[<ffffffff810d4fa3>] timer_cpu_notify+0x53/0x12
That hunk is a leftover from an earlier iteration and went unnoticed
so far.
Restore the previous code which was obviously correct.
Fixes: 0eeda71bc30d 'timer: Replace timer base by a cpu index'
