I think he's most likely Zuko's grandson.
Here's what I have worked out (and this is all I am saying on this subject, before I put my foot in my mouth again)
According to the Wiki Zuko is currently 87 or so. Iroh II appears to be in his 20-30's. If you assume him to be 35 (what I would say is the outside edge of how old someone could be and still look that young) Zuko would have had to have had him when he was 52. In terms of Zuko himself that is really no problem. The problem, if there is one, comes into play with Mai. When Zuko was 52, Mai would have been about 51 (the wiki says she is about 1 year younger than Zuko). It is of course perfectly possible for a woman to bear children when she is that old, but it is on the tail end of what is generally considered the fertile period (I looked it up and it seems the average for menopause is around the late 40's to early 50's) And since Iroh II is likely quite a bit younger than 35 (closer to 30 or even 25) Mai would have been even older, and even more likely to be past childbearing age. And there is no record (as far as I know) of Mai dying young and/or Zuko taking a second wife* (they would have mentioned by now if he had, I think) So "grandson" seems more likely.
* I say and/or because The Fire Nation has a lot of traits in common with Imperial China, and in Imperial China, it was perfectly legal and acceptable for those of sufficient wealth and status to have multiple wives. An emperor (which would be roughly the equvalent rank to Fire Lord) could have hundreds (not counting his concubines) I rather doubt polygamy is done in the Fire Nation, but it is not utterly impossible.
