ibmvnic: Free rwi on reset success

Free the rwi structure in the event that the last rwi in the list
processed successfully. The logic in commit 4f408e1f ("ibmvnic:
retry reset if there are no other resets") introduces an issue that
results in a 32 byte memory leak whenever the last rwi in the list
gets processed.
