These are exactly the kinds of CoverityScan fixes I really do not want
to see.
Initializing ret to zero is not going to fix the problem.
This function gets error pointers back from the functions that are
used to obtain the ibmr pointer. Therefore if there is a problem
ibmr won't be NULL, it will be an error pointer.
Therefore, the real problem is that the code isn't checking if
ibmr encodes error value.
