hostap 0.2.3 sends disassoc/deauth while in monitor mode

Hi Jouni, Luis, Margit, Andreas,

I am playing with hostap, prism54 and acx100 in the same box
simultaneously, and as expected, I see a lot of interesting things :)

Lets start with hostap.

hostap is the most mature driver, and so far, I've seen only
one buglet while hostap is in monitor mode.

It looks like while it was in AP mode (because it is default
mode for hostap), acx100 or prism54 associated with it.

And now, sitting in monitor mode, hostap all of a sudden
sends disassoc/deauth to the poor STA, which confuses
young and inexperienced acx100 driver:
