wifi: rtw88: Fix the random "error beacon valid" messages for USB
All the USB devices have a problem in AP mode: uploading the updated
beacon to the chip's reserved page can randomly fail:
[34996.474304] rtw88_8723du 1-2:1.2: error beacon valid
[34996.474788] rtw88_8723du 1-2:1.2: failed to download drv rsvd page

[35023.200875] rtw88_8723du 1-2:1.2: failed to download beacon
[35478.680547] rtw88_8723du 1-2:1.2: error beacon valid
[35478.681023] rtw88_8723du 1-2:1.2: failed to download drv rsvd page
Disable some beacon-related hardware functions before uploading the
beacon and enable them again after.
Tested with RTL8723DU, RTL8812BU, RTL8822CE.
