wifi: iwlwifi: mld: force the responder to use the full bandwidth

When a soft AP is started, it may not use the full configured
bandwidth (e.g. if no station is connected). As a result, the
responder will not support the configured bandwidth. Since the
responder supports ranging with unassociated stations, there is
no indication to the driver when the full bandwidth should be enabled.
Fix it by configuring the AP to always use the full bandwidth when a
responder is supported.
