From: Ilan Peer <ilan.peer@intel.com>

In case the link puncturing is changed such that the channel
is no longer punctured, configure the FW correctly indicating
the EHT parameters changed (with a 0 punctured map).

Allow EHT parameters configuration only when the link really
supports EHT.

Fixes: 55eb1c5fa4b2 ("wifi: iwlwifi: mvm: add support for the new LINK command")
