[TIPC]: Fix simple sparse warnings
Tried to run the new tipc stack through sparse. Following patch fixes all cases where 0 was used as replacement of NULL. Use NULL to document this is a pointer and to silence sparse. This brough sparse warning count down with 127 to 24 warnings. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Per Liden <per.liden@ericsson.com> Signed-off-by: David S.
