iwlwifi: mvm: use CTS to Self if firmware allows it
Newer firmware fixed a bug that prevented to use CTS to self. Firmwares with API greater than 8 have this bug fixed. Enable the feature for these firmwares only. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
