Similarly, there's no reason to tear down aggregations on resume, as they should have been torn down on suspend if needed. However, since the reconfiguration flow is shared with HW restart, tear down aggregations on reconfiguration when we are not resuming. To keep things working after non-wowlan suspend, keep clearing the WLAN_STA_BLOCK_BA flag.
