From: Eliad Peller <eliadx.peller@xxxxxxxxx>
in case of "any" wowlan trigger, there is no reason to tear down
aggregations, as we want the device to continue working normally.
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 only when we are not resuming.
To keep things working after non-wowlan suspend, keep clearing the
WLAN_STA_BLOCK_BA flag.
