The iwl3945 and iwl4965 devices share some common structure, but with a
lot of difference split all over. Currently the two drivers share a lot
of headers and use ugly preprocessor magic to manage the difference.
This patch keeps two entirely separate copies of the headers to get rid
of these hacks an ease future development.

This patch do the following 2 things:
1. Make sure we don't add rate 60M part of supported rate in proble request,
some AP does not like that.
2. It is wrong to set priv->active_rate in this function, this will set
it to all avialable rates which might overwrite the mode supported rate.
priv->active_rate should be set by only from iwl_set_rate.

Prior to this patch, iwlwifi would always use the first
registered rate control algorithm which, depending on system
setup, could be anything. After the mac80211 patch to make
the simple algorithm built-in, it would always be simple.
This has always been a bug in iwlwifi.
This fixes it by requesting that mac80211 selects the right
rate control algorithm.
