stop dirty tracking just at the end of migration (Glauber Costa)

If there is still work to do, it is not safe to assume we
can end the dirty tracking. Specifically, kvm can update the dirty
tracking log inside ram_save_block(), leaving pages still out of sync
if we go with the current code.

Based on a patch by Yaniv Kamay
