[PATCH] ipw2200: add monitor and qos entries to Kconfig

I have made a stupid copy&paste error: QoS option is named IPW_QOS not
IPW2200_MONITOR. Spotted by Daniel Paschka, thanks.

Add the following config entries for the ipw2200 driver to
drivers/net/wireless/Kconfig
 * IPW2200_MONITOR
   enables Monitor mode
 * IPW_QOS
   enables QoS feature - this is under development right now, so it depends
upon EXPERIMENTAL
