Issue: Host is sending VDEV_INSTALL_KEY command without validating vdev state. If there is channel change request, in function lim_change_channel on WLAN_VDEV_SM_EV_CSA_COMPLETE, WLAN_VDEV_SM_EV_RESTART_REQ i.e vdev restart request is triggred to fw and if there is any ongoing sta connection parallely, then it may send vdev install without validating vdev state. If firmware receives VDEV_INSTALL_KEY, it stops critical channel request. Firmware sends VDEV_START_RESPONSE/VDEV_RESTART_RESPONSE once it gets channel grant. If host sends VDEV_INSTALL_KEY to fw before it gets channel grant then fw stops channel request and does not send VDEV_RESTART_RESPONSE. Fix: Valdiate vdev state before sending VDEV_INSTALL_KEY command. In function wlan_hdd_add_key_sap validate the state of vdev and send command only if vdev is in between restarting state.
