io_uring/bpf-ops: implement bpf ops registration
Implement BPF struct ops registration. It's registered off the BPF
path, and can be removed by BPF as well as io_uring. To protect it,
introduce a global lock synchronising registration. ctx->uring_lock can
be nested under it. ctx->bpf_ops is write protected by both locks and
so it's safe to read it under either of them.
