wifi: iwlwifi: mvm: don't send a 6E related command when not supported
In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: don't send a 6E related command when not supported MCC_ALLOWED_AP_TYPE_CMD is related to 6E support. Do not send it if the device doesn't support 6E. Apparently, the firmware is mistakenly advertising support for this command even on AX201 which does not support 6E and then the firmware crashes.
