fix(esp_wifi) : Fix collection of issues in sta roam and scan.

1) Fix issue during split scan to allow for data tx.
2) Fix issue when parsing wpa_ie to set correct authmode when AP
supports both WPA_EAP and WPA_EAP_SHA256 authmode.
Closes https://github.com/espressif/esp-idf/issues/11202
3) Fix an occasional crash during sta roam.
4) Add home_channel_dwell_time to wifi_scan_config_t. This allows
configuration of the time spent between scanning consecutive
channels for tx.
5) Adds a obss scan timer disarm when a sta disconnects from an AP
