X-Git-Tag: v8.0.0-rc0~47^2~1

migration/colo: Improve an x-colo-lost-heartbeat error message

The QERR_ macros are leftovers from the days of "rich" error objects.
We've been trying to reduce their remaining use.

Get rid of a use of QERR_FEATURE_DISABLED, and improve the somewhat
imprecise error message

    (qemu) x_colo_lost_heartbeat
    Error: The feature 'colo' is not enabled

to

    Error: VM is not in COLO mode
