[PATCH] CONFIG_WIRELESS_EXT is neccessary after all

WARNING: /lib/modules/2.6.17-mm2/kernel/net/ieee80211/ieee80211.ko
needs unknown symbol wireless_spy_update

Someone removed the `#ifdef CONFIG_WIRELESS_EXT' from around the callsite
in net/ieee80211/ieee80211_rx.c and didn't update Kconfig appropriately.

The offending patchset seems to be 35c14b85
which is tittled

  [PATCH] ieee80211: remove unnecessary CONFIG_WIRELESS_EXT checking

After a quick look it seems that wireless_spy_update() lives in
net/core/wirless.c, and that file is only compiled if
CONFIG_WIRELESS_EXT is set. Perhaps this is Kconig work, but
in the mean time here is a reversal of the recent change.
