[PATCH v2] timer: Forward timer base before migrating timers

In case when timers are migrated to a CPU, after it exits idle, but before timer base is forwarded, either from run_timer_softirq()/mod_timer()/add_timer_on(), it's possible that migrated timers are queued, based on older clock value. This can cause delays in handling those timers. For example, co
