But patch 09/18 "blockdev: switch blockdev_replace() to use QMP peer"
already adds an import for vm_qmp_peer and patches 13/18 "block job:
switch qemu_drive_mirror_monitor() to use QMP peer" and 14/18 "blockdev:
switch blockdev_delete() to use QMP peer" switched the functions to
support having a QMP peer already, so what is the issue?
