rcu: Advance callbacks after migration

When migrating callbacks from a newly offlined CPU, we are already
holding the root rcu_node structure's lock, so it costs almost nothing
to advance and accelerate the newly migrated callbacks.  This patch
therefore makes this advancing and acceleration happen.
