UPSTREAM: bpf: Fix bpf_ringbuf_output() signature to return long

Browse source 
Due to bpf tree fix merge, bpf_ringbuf_output() signature ended up with int as
a return type, while all other helpers got converted to returning long. So fix
it in bpf-next now.

Fixes: b0659d8a950d ("bpf: Fix definition of bpf_ringbuf_output() helper in UAPI comments")
