Thanks for quick reply.

I've tried your suggestion on the fly: 

modprobe -rv iwlwifi
modprobe iwlwifi bt_coex_active=0

After this, I get "N" from "more
/sys/module/iwlwifi/parameters/bt_coex_active", but it seems not to take any
effect on device functioning nor on the kernel messages. 
Is this what you meant? BTW, the bluetooth seems to work.

Best,
Piotr
