nvme_set_features() callers seem to expect that passing NULL as the result pointer is acceptable. Teach nvme_set_features() not to try to write to the NULL address. For symmetry, make the same change to nvme_get_features(), despite the fact that all current callers pass a valid result pointer. I assume that this bug hasn't been reported in practice because the callers that pass NULL are all in the SCSI translation layer and no one uses the relevant operations.
