[PATCH] hostapd: safe call to hostapd_config_check_bss_6g()

Subject: [PATCH] hostapd: fix incorrect call to hostapd_config_check_bss_6g()

In ap_drv_ops.c, the call to hostapd_config_check_bss_6g() is executed
unconditionally. However, it should only be used when the BSS is actually
configured on a 6 GHz operating class. This leads to false configuration
errors in setups where the 6 GHz BSS has proper settings but other bands
(2.4/5 GHz) share the same config structure.

This patch adds the missing is_6ghz_op_class() condition, mirroring how
it's already used elsewhere in the codebase (e.g. in ap_config.c).

Fix verified on OpenWRT 24.10-SNAPSHOT using Mediatek Wi-Fi 7 hardware.
