Summary
wifi: mac80211: fix WARN_ON for monitor mode on some devices
Details

In the Linux kernel, the following vulnerability has been resolved:

wifi: mac80211: fix WARN_ON for monitor mode on some devices

On devices without WANTMONITORVIF (and probably without channel context support) we get a WARN_ON for changing the per-link setting of a monitor interface.

Since we already skip APVLAN interfaces and MONITOR with WANTMONITORVIF and/or NOVIRTUAL_MONITOR should update the settings, catch this in the link change code instead of the warning.
