It is possible that the device driver API pointer is null. For example if the device driver returns an error, the device code will make the API pointer NULL so that the API would not be used. This can cause errors in networking code where we typically do not check the NULL value. Fixes #15003 Signed-off-by: Jukka Rissanen <jukka.rissanen@linux.intel.com>
