Stop overwriting the pre-assigned cookie in wil_p2p_listen(),
wil_cfg80211_mgmt_tx(), and wil_cfg80211_probe_peer().
For remain_on_channel, store the pre-assigned cookie in p2p->cookie
instead of incrementing it. All cancel and expiry callbacks already
read from p2p->cookie so they pick up the correct value.
For mgmt_tx, remove the defensive "cookie ? *cookie : 0" guard;
cfg80211 guarantees a non-NULL cookie pointer.
For probe_peer, store the pre-assigned cookie in req->cookie instead
of the CID value. The CID is still available via req->cid for STA
lookup in wil_probe_client_handle().
