[ Upstream commit ebea22c7f1b2f06f4ff0719d76bd19830cf25c9f ]
When Wi-Fi is scanning at 2.4GHz, PTA will abort almost all the BT request. Once the Wi-Fi slot stay too long, BT audio device can not get enough data, audio glitch will happened. This patch limit 2.4Ghz Wi-Fi slot to 80ms while Wi-Fi is scanning to avoid audio glitch.
