hw/qdev: Check machine_hotplug_handler in hotplug_unplug_allowed_common

Commit 03fcbd9dc508 ("qdev: Check for the availability of a hotplug
controller before adding a device") says:

> The qdev_unplug() function contains a g_assert(hotplug_ctrl)
> statement, so QEMU crashes when the user tries to device_add +
> device_del a device that does not have a corresponding hotplug
> controller.

> The code in qdev_device_add() already checks whether the bus has a
> proper hotplug controller, but for devices that do not have a
> corresponding bus, here is no appropriate check available yet. In that
> case we should check whether the machine itself provides a suitable
> hotplug controller and refuse to plug the device if none is available.

However, it forgot to add the corresponding check to qdev_unplug().

Check the machine hotplug handler once in the common
qdev_hotplug_unplug_allowed_common() helper so both hotplug
and hot-unplug path are covered.
