tipc: make media address offset a common define
With the exception of infiniband media which does not use media offsets, the media address is always located at offset 4 in the media info field as defined by the protocol, so we move the definition to the generic bearer.h Signed-off-by: Erik Hugne <erik.hugne@ericsson.com> Signed-off-by: David S.
