From: Jesper Dangaard Brouer <bro...@redhat.com>
Commit 77361825bb01 ("bpf: cpumap use ptr_ring_consume_batched") changed
away from using single frame ptr_ring dequeue (__ptr_ring_consume) to
consume a batched, but it uses a locked version, which as the comment
explain isn't needed.
Change to use the non-locked version __ptr_ring_consume_batched.
Fixes: 77361825bb01 ("bpf: cpumap use ptr_ring_consume_batched")
