Subject: [PATCH 02/13] wifi: ath12k: indicate NON MBSSID vdev by default during vdev start

When any VDEV is started, MBSSID flags are passed to firmware to
indicate if its a MBSSID/EMA AP vdev. If the interface is not an AP
or if the AP doesn't support MBSSID, the vdev needs to be brought up
as a non MBSSID vdev. Set these flags as a non MBSSID AP by default
which can be updated as and when MBSSID support is added in ath12k.
