7878a5a4fc iwlwifi: enhance WPA authenication stability
This patch enhanced WPA authenication stability by avoiding scan
immediately followed by association. We don't do any scanning right
after association in next several seconds. This will allow WPA

- Remove HT code from iwl-3945.h - it is not needed here as 3945

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.
