qcacld-2.0 to qcacld-3.0 propagation
When the driver is in SoftAP mode when it is unloaded,
and if many clients are connected,
sometimes not all clients can gracefully disconnect.
In this case the IPA HW pipes are not cleaned up properly,
and subsequent pipe setup will usually fail.
To avoid a bad pipe configuration, before unloading driver,
check the pipe status and if the pipes are not closed properly,
shutdown the pipes forcefully.
