Change hotspot security to WPA3-Transition when switching from 6GHz

When changing hotspot to 6GHz, we auto-set the security to WPA3-SAE. However, we don't do the reverse when changing out of 6GHz, which may cause legacy devices to be unable to connect. Instead, always revert back to WPA3-Transition when switching out of 6GHz.
