When migrating both memory and storage, we need to make sure block jobs
are finished after the virtual CPUs get paused at the end of migration
but before QEMU completes the migration otherwise QEMU may die with
_co_do_pwritev: Assertion `!(bs->open_flags & 0x0800)' failed
This is a libvirt side of the QEMU fix from Dr. David Alan Gilbert:

Applicable on top of my "Preparation for new QEMU migration states"
series I sent yesterday.
Jiri Denemark (3):
qemu: Add support for migrate-continue QMP command
qemu: Add pause-before-switchover migration capability
qemu: Enabled pause-before-switchover migration capability
