sched: fix freeing per-vcpu data in sched_move_domain()

In case of an allocation error of per-vcpu data in sched_move_domain()
the already allocated data is freed just using xfree(). This is wrong
as some schedulers need to do additional operations (e.g. the arinc653
scheduler needs to remove the vcpu-data from a list).

So instead xfree() make use of the sched_free_vdata() hook.
