zd1211 stability issue on 2.6.25

[matthieu castet <castet.matthieu@free.fr>]

Hi,

I am using a zd1211 dongle [1] on 2.6.25 in wpa mode. Sometimes I got
disconnection [2]. But after that scanning seems to doesn't work anymore
[3].
This cause wpa_supplicant to do an endless lop try to find the AP in the
scan result and there no reconnection.
Only a ifconfig wlan0 down, ifconfig wlan0 up make work again scanning.

This make the dongle not usable.
