Subject: [PATCH] Fix #1441: Do not unplug controllers when the mirroring is
 finished

This should not be needed since we call 'block-job-complete' before
in qemu_drive_mirror_monitor(), and after benchmarking it does not
appear to be needed nor provide a measurable improvement when shutting
down the source.
