Re: [libvirt] [PATCH] qemu: Adjust the cur_ballon on coldplug/unplug of dimms

The cur_balloon also increases/decreases with dimm hotplug/unplug. To be consistent, adjust the value for coldplug too. This was inconsistently taken care when cur_ballon != memory to begin with. The patch fixes it irrespective of that.
