bpf: Use migrate_disable/enable in array macros and cgroup/lirc code.
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.
Including the code paths that go via __bpf_prog_run_save_cb().
