wifi: mac80211_hwsim: fix race condition in pending packet
A pending packet uses a cookie as an unique key, but it can be duplicated
because it didn't use atomic operators.
And also, a pending packet can be null in hwsim_tx_info_frame_received_nl
due to race condition with mac80211_hwsim_stop.
For this,
* Use an atomic type and operator for a cookie
* Add a lock around the loop for pending packets
