[ Upstream commit c2f46814521113f6699a74e0a0424cbc5b305479 ]
After the previous similar bugfix there was another bug here,
if no VHT elements were found we also disabled HE. Fix this to
disable HE only on the 5 GHz band; on 6 GHz it was already not
disabled, and on 2.4 GHz there need (should) not be any VHT.
Fixes: 57fa5e85d53c ("mac80211: determine chandef from HE 6 GHz operation")
