qcacld-2.0: Fix invalid peer create after vdev down
In a SNS case, driver receives ASSOC Req during the SAP Stopping. The SAP stopping will issue WMI_VDEV_DOWN_CMDID WMI command to firmware. And ASSOC req frame processing will issue a WMI_PEER_CREATE_CMDID WMI command to firmware. Then the firmware crash happens because firmware can't find the necessary BSS information to create the peer. Firmware doesn't support peer create after BSS down. The fix is to ignore the ASSOC Req frame while the deleting BSS is ongoing. Change-Id: Ib517642da4fc6b4778ef1ce4e6afd92fa3edb112 CRs-Fixed: 1053809
