[Shiji Yang]

From: Shiji Yang <yangshiji66 at qq.com>

The change_beacon() API has been updated since the 6.7 kernel. Ref:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v6.9.9&id=66f85d57b7109baf8a7d5ee04049ac9412611d35

Fix build error:
../rtl8812au-ct-2022.10.26~9b2b203a/os_dep/linux/ioctl_cfg80211.c:5984:26: error: initialization of 'int (*)(struct wiphy *, struct net_device *, struct cfg80211_ap_update *)' from incompatible pointer type 'int (*)(struct wiphy *, struct net_device *, struct cfg80211_beacon_data *)' [-Werror=incompatible-pointer-types]
 5984 |         .change_beacon = cfg80211_rtw_change_beacon,
      |                          ^~~~~~~~~~~~~~~~~~~~~~~~~~
../rtl8812au-ct-2022.10.26~9b2b203a/os_dep/linux/ioctl_cfg80211.c:5984:26: note: (near initialization for 'rtw_cfg80211_ops.change_beacon')
