wifi: mac80211: update radar_required in channel context after channel switch
Currently, when a non-DFS channel is brought up and the bandwidth is expanded from 80 MHz to 160 MHz, where the primary 80 MHz is non-DFS and the secondary 80 MHz consists of DFS channels, radar detection fails if radar occurs in the secondary 80 MHz. When the channel is switched from 80 MHz to 160 MHz, with the primary 80 MHz being non-DFS and the secondary 80 MHz consisting of DFS channels, the radar required flag in the channel switch parameters is set to true. However, when using a reserved channel context, it is not updated in sdata, which disables radar detection in the secondary 80 MHz DFS channels. Update the radar required flag in sdata to fix this issue when using a reserved channel context.
