FROMGIT: wifi: cfg80211: Prevent cfg80211_wext_siwencodeext() on MLD

Browse Source 
Currently, MLO support is not added for WEXT code and WEXT handlers are
prevented on MLDs. Prevent WEXT handler cfg80211_wext_siwencodeext()
also on MLD which is missed in commit 7b0a0e3c3a88 ("wifi: cfg80211: do
some rework towards MLO link APIs")
