The four callback functions deferference the pointers without test. As ipoib_get_iflink failed, it is a good reason to fix the other three functions. Those functions will return zero on error, as valid ifindex greater than zero.
I understand that those simple patches should be emerged into a single patch. However, those files have be maintained by different maintainers. So, I split it for review. It also will be convenient to remove one or more patches with the rest not be affected.
