It is an odd construct, but I think this is correct.  What it is actually
saying is that, given that we don't have an external resistor, we care
that the tia-gain-ohm isn't set (otherwise it wouldn't matter).

From the docs
  - ti,external-tia-resistor: if the property ti,tia-gain-ohm is not defined this
    needs to be set to signal that an external resistor value is being used.

So, it might be ideal to say that tia-gain-ohm is not defined and we do
not have an external resistor specified.

So not wrong, but could be more informative!  So perhaps a follow up patch
to tidy that up would be good.
