When QEMU reports failed or cancelled migration, we don't need to
send
it migrate_cancel QMP command. But in all other error paths, such as if
we detect broken connection to a destination daemon or something else
happens inside libvirt, we need to explicitly send migrate_cancel
command instead of relying on the migration to be implicitly cancelled
when destination QEMU is killed.
Because we were not doing so, one could end up with a paused domain
after failed migration.
