[Qemu-devel] [PULL 09/12] migration: Fix postcopy bw for recovery

[Dr. David Alan Gilbert (git)]

From: Peter Xu <address@hidden>

We've got max-postcopy-bandwidth parameter but it's not applied
correctly after a postcopy recovery so the recovered migration stream
will still eat the whole net bandwidth.  Fix that up.
