iwlwifi: dvm: don't enable CTS to self
We should always prefer to use full RTS protection. Using CTS to self gives a meaningless improvement, but this flow is much harder for the firmware which is likely to have issues with it. CC: <stable@vger.kernel.org> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
