qcacld-3.0: Update defconfig for qca6174

The functions hdd_sysfs_create_adapter_root_obj() and
hdd_sysfs_destroy_adapter_root_obj() are declared but not
implemented if CONFIG_WLAN_SYSFS is not defined but
CONFIG_FEATURE_BECN_STATS is defined. Do not enable
CONFIG_FEATURE_BECN_STATS if CONFIG_WLAN_SYSFS is not defined.
