Selvaraj, Sridhar 171e225474 qcacld-3.0: Check if vdev is created before LL stats query ... qcacld-2.0 to qcacld-3.0 propagation As part of "change iface" in HDD, host does close session (VDEV DELETE) and as part of "start ap", host invokes open session(VDEV CREATE). Link Layer(LL) stats query is received in host driver in a corner/race condition between the events "change iface" and "start ap" which leads to an exception issue in firmware since FW receives REQUEST_LINK_STATS WMI for a deleted VDEV. This fix adds a boolean variable vdev_active to vdev structure(wma_txrx_node), which is set to true once vdev is created. vdev_active is checked for TRUE before sending LL stats query to FW with WMI command.
