bpf/tests: Use migrate disable instead of preempt disable
Replace the preemption disable/enable with migrate_disable/enable() to reflect the actual requirement and to allow PREEMPT_RT to substitute it with an actual migration disable mechanism which does not disable preemption. [ tglx: Switched it over to migrate disable ] Signed-off-by: David S.
