cld: tlshim: Fix kernel crash on driver unload
Loading and unloading the driver iteration during the data traffic,
is leading to NULL pointer dereference. There is race condition
between assoc completion and driver unload that leads to wakeup the
stopped netif queues. Fix that by dropping the trasmitted frames
when the unload in progress.
