wifi: mac80211: skip default WMM setup for AP_VLAN links

AP_VLAN interfaces are never passed to the driver, so setting default WMM
parameters on their links trips the check-sdata-in-driver warning in
drv_conf_tx(), as well as in the BSS_CHANGED_QOS link info notification.
Skip it, matching the existing AP_VLAN handling in this function.
