[Qemu-devel] [PATCH] migration: Fix migration state update issue

[Liang Li <liang.z.li@intel.com>]

If live migration is very fast and can be completed in 1 second,
the dirty_sync_count of MigrationState will not be updated.
Then you will see "dirty sync count: 0" in qemu monitor even if
the actual dirty sync count is not 0.
