wifi: ath12k: Add support to handle reason inactivity STA kickout event for QCN9274/IPQ5332

Browse Source 
Currently, when the non-AP STA connected to the AP STA, and the AP STA goes
down or becomes inactive without indication, firmware detects the beacon
miss and sends the WMI event WMI_PEER_STA_KICKOUT_EVENTID with reason as
INACTIVITY. The host driver handles this event as low ACK and reports it to
the mac80211 driver.

However, the expectation is that non-AP STA should be disconnected from
AP STA instantly once it receives the STA kickout event with reason of
inactivity.

Trigger a disconnect from AP STA through beacon miss handling upon
receiving non-AP STA peer kickout event with reason code inactivity.

Replace the helper function ath12k_mac_get_ar_by_vdev_id() with
ath12k_mac_get_arvif_by_vdev_id() due to the following reasons.

1. Check the station VIF type for handling the beacon miss.

2. Retrieve the proper ar from the arvif by checking the vdev_id with
   vdev_map and link_map lookup which is needed for the MLO case in the
   following patch.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.4.1-00199-QCAHKSWPL_SILICONZ-1
