wifi: iwlwifi: mvm: don't send a 6E related command when not supported
[ Upstream commit 323156c3541e23da7e582008a7ac30cd51b60acd ]
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.
Fixes: 0d2fc8821a7d ("wifi: iwlwifi: nvm: parse the VLP/AFC bit from regulatory")
Closes: https://bugzilla.kernel.org/show_bug.cgi?id=220804
