timers: Clear pending_map on CPU hotplug
CPU hotplug migration leaves pending_map bits set on the outgoing CPU
while its wheel vectors are empty. After re-online, a later next_expiry
recalc can treat those empty buckets as pending and temporarily pull
next_expiry forward until collect drains the bits.
Clear pending_map under the base lock after migration in timers_dead_cpu().
