[PATCH HID 0/4] HID: selftest fixes after merge into 6.11-rc0 tree

[Benjamin Tissoires]

After HID-BPF struct_ops was merged into 6.11-rc0, there are a few
mishaps:
- the bpf_wq API changed and needs to be updated here
- libbpf now auto-attach all the struct_ops it sees in the bpf object,
  leading to attempting at attaching them multiple times

Fix the selftests but also prevent the same struct_ops to be attached
more than once as this enters various locks, confusions, and kernel
oopses.
