ucc_geth: Fix full TX queue processing
commit 34692421bc7d6145ef383b014860f4fde10b7505 upstream.
commit 7583605b6d29f1f7f6fc505b883328089f3485ad ("ucc_geth: Fix empty
TX queue processing") fixed empty TX queue mishandling, but didn't
account another corner case: when TX queue becomes full.
Without this patch the driver will stop transmiting when TX queue
becomes full since 'bd == ugeth->txBd[txQ]' actually checks for
two things: queue empty or full.
Let's better check for NULL skb, which unambiguously signals an empty
queue.
