That will cause the coex mechanism being skipped unexpectedly. Coex only wanted to keep the TDMA table from being changed by BT side. So, check the freeze and reason, if the coex reason is coming from BT info, skip it, to make sure the coex triggered by Wifi itself can work. This is required for the AP mode, while the control flow is different with STA mode. When starting an AP mode, the AP mode needs to start working immedaitely after leaving IPS, and the freeze flag could be raised. If the coex info is skipped, then the AP mode will not set the antenna owner, leads to TX stuck.
