The iwlwifi drivers both make mac80211 accept an arbitrary number of
virtual interfaces while in reality they can only support one. Fix that.

Please apply this to 2.6.24 as that has userspace interface (nl80211) to
add/remove virtual interfaces. There's *LOTS* to be done for proper
support, e.g. monitor mode is completely messed up, but this at least
doesn't let the user create multiple interfaces that won't work.
Please push to Jeff for .24.
