wifi: ath12k: add processing for TWT disable event
When ath12k send TWT disable command to firmware, firmware will return a
TWT disable event to ath12k. Through the analysis of TWT disable event
status, we can easily obtain the status of TWT disable command. It can be
more convenient to debug TWT.
This patch works with WCN7850 and QCN9274.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
