wifi: rtw88: coex: Solve LE-HID lag & update coex version to 26020420

Browse Source 
When Wi-Fi enters power save, the register value can not be read
correctly. If mechanism take the wrong information to make decision,
it will run with wrong parameters. It leads Bluetooth low-energy
HID lag. Add logic to isolate the wrong register state.

BTCOEX Version: 26020420-2020
Desired_BT_Coex_Ver: 0x20
Desired_WL_FW_Ver: 9.9.X
