wifi: rtw89: wow: Add Basic Rate IE to probe request in scheduled scan mode
[ Upstream commit 37c23874d13eb369d8b384a1ce5992ff6c23d56f ]
In scheduled scan mode, the current probe request only includes the SSID
IE, but omits the Basic Rate IE. Some APs do not respond to such
incomplete probe requests, causing net-detect failures. To improve
interoperability and ensure APs respond correctly, add the Basic Rate IE
to the probe request in driver.
