migration: do cleanup operation after completion
Because of the patch 3ea3b7fa9af067982f34b of kvm, now the migration_end() is a time consuming operation, which takes about dozens of milliseconds, and will prolong VM downtime. Such an operation should be done after migration completion. For a VM with 8G RAM, this patch can reduce the VM downtime about 32 ms during live migration.
