Simplification of checking Diagnostic response.
A CAN message will be considered as a Diagnostic response when its arbitration ID is between standardized 0x7E8 and 0x7EF. Checking which request belong to that response will done in later methods Change-Id: I7a093edf44b62a4552b90fe3d8935f94dc677cf4 Signed-off-by: Romain Forlot <romain.forlot@iot.bzh>
