bpf: Do not walk twice the map on free
If someone stores both a timer and a workqueue in a map, on free
we would walk it twice.
Add a check in array_map_free_timers_wq and free the timers and
workqueues if they are present.
Fixes: 246331e3f1ea ("bpf: allow struct bpf_wq to be embedded in arraymaps and hashmaps")
