In ntb_netdev_open, when ntb_transport_rx_enqueue fails the skb that was
attempting to be enqueued is not freed. Free this skb on the
ntb_transport_rx_enqueue error.

If list_for_each_entry exits without finding the ntb_device, the dev
pointer will not be NULL. Thus the check will never be true and the
code will not exit when it should. Correct this by adding a bool to
determine when the device is found, otherwise exit in good fashion.

The ntb_netdev device is not removed from the global list of devices
upon device removal. If the device is re-added, the removal code would
find the first instance and try to remove an already removed device.

There is a race between disabling and enabling the tx queue, resulting
in tx timeouts. Since all the tx timeout does is re-enable the tx
queue, simple remove the start/stop of the queue and the tx timeout
routine.

If ntb_netdev is unable to pass a new skb to the ntb transport for
future rx packets, it should free the newly alloc'ed skb in the error
case. Found by Kernel memory leak detector.

These are now gone from the kernel, so remove them from the newly-added
drivers before they start to cause build errors for people.
