We add a scanning check to avoid entering IPS after ROC (remain on channel) during scanning. Additionally, When P2P scanning, the flow is `1. p2p_listen step` and `2. configure filter` and `3. p2p_scan starts` in wpas, but in kernel, cfg80211 uses another workqueue to notify driver the filter change, so sometimes we see (1 > 3 > 2), that will cause Rx filter related to scan to be cleared. Therefore, we add a scanning check when configure filter to avoid scan results to be filtered. Finally, we cancel the ROC delayed workqueue before entering ROC to avoid entering twice, which might cause leaving ROC too early.
