iwlwifi: range checking issue

commit 8e1a53c615 upstream.

IWL_RATE_COUNT is 13 and IWL_RATE_COUNT_LEGACY is 12.

IWL_RATE_COUNT_LEGACY is the right one here because iwl3945_rates
doesn't support 60M and also that's how "rates" is defined in
iwlcore_init_geos() from drivers/net/wireless/iwlwifi/iwl-core.c.

        rates = kzalloc((sizeof(struct ieee80211_rate) * IWL_RATE_COUNT_LEGACY),
                        GFP_KERNEL);
