We only want to disable this if bt_disable_cnt is >= 2.

Btw, that patch also introduced Sparse warning but I don't know how to
address it.

I agree that bt_disabled needs to be initialized. Actually, I would have
expected an unitialized variable warning out of gcc.
Earlier today, I finished applying the rest of the btcoex patches from Realtek
and now have a clean Sparse run. I never saw that message, and I certainly do
not understand it either.
