fea903ecd7 ntb_netdev: Fix list_for_each_entry exit issue
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.

ntb_netdev: remove from list on exit
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.

d723485cb4 ntb_netdev: remove tx timeout
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.

765ccc7bc3 ntb_netdev: correct skb leak
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.

78a61ab79a ntb: remove __dev* markings
These are now gone from the kernel, so remove them from the newly-added
drivers before they start to cause build errors for people.
