wifi: ath12k: Set WDS vdev parameter for 4-address station interface

Browse Source 
Set WDS vdev parameter during station interface creation to enable
4-address mode. Unlike AP interfaces that set peer-specific 4-address
mode parameters after receiving 4-address frames from stations, station
interfaces must send all data frames in 4-address mode immediately after
association, including 4-address NULL frames.

Firmware requires 4-address notification for station interfaces during
vdev creation. Configure the WDS vdev parameter for station interfaces.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.6-01243-QCAHKSWPL_SILICONZ-1
