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.
