Based upon a bug report by Alexey Dobriyan, the patch is
also tested by him and confirmed to fix the problem.

Packet flow during link state events should not be done by
waking and stopping the TX queue anyways, that is handled
transparently by netif_carrier_{on,off}().

So, remove the netif_{wake,stop}_queue() calls in the link
check code, and add the necessary netif_start_queue() call
to atl1_up().
