Subject: [PATCH 5.14 367/432] iwlwifi: mvm: Do not use full SSIDs in 6GHz scan

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

[ Upstream commit deedf9b97cd4ef45da476c9bdd2a5f3276053956 ]

The scan request processing populated the direct SSIDs
in the FW scan request command also for 6GHz scan, which is not
needed and might result in unexpected behavior.

Fix the code to add the direct SSIDs only in case the scan
is not a 6GHz scan.
