Subject: bpf: Update bpf_get_smp_processor_id() documentation
Patch-mainline: v5.16-rc1
Git-commit: 336562752acc1a723f9a24b5b8129ae22e0478c6
References: jsc#PED-1377

BPF programs run with migration disabled regardless of preemption, as
they are protected by migrate_disable(). Update the uapi documentation
accordingly.
