Subject: [PATCH] ath11k: Fix build warning without CONFIG_IPV6

drivers/net/wireless/ath/ath11k/mac.c:8175:13: error: ‘ath11k_mac_op_ipv6_changed’ defined but not used [-Werror=unused-function]
 static void ath11k_mac_op_ipv6_changed(struct ieee80211_hw *hw,
             ^~~~~~~~~~~~~~~~~~~~~~~~~~

Wrap it with #ifdef block to fix this.
