Backport following Wifi fixes:
1. Optimize WiFi sleep in WiFi/BT coexist mode
I> If any data TX/RX in WiFi slice, force wakeup next TBTT
II> Increase active timeout to coex TBTT to avoid sleep in WiFi slice
2. Fix esp_wifi_stop() crash
esp_wifi_stop() crashes if it's called when WiFi is not initialized.
3. Fix WiFi log print level
4. Return fails if AP's configuring AP channel is out of range
5. esp_wifi_sta_get_ap_info() returns actual values of group ciphers
