Niklas Cassel 7ce5dd62f7 nvme/identify: use calloc to allocate zone report buffer ... When support for printing the zone report was added, the zone report buffer was allocated using calloc(). This was intentionally changed to a malloc in commit 5ef79a17ec ("examples/nvme/identify: add an option to dump the full zns zone report"). While we shouldn't need to zero the buffer, since the drive should write the "Number of Zones" field in zone report header, and we should never read zone descriptors beyond this value, the ZNS spec also states that reading beyond the last zone descriptor has undefined results. Considering that "Number of Zones" field in the zone report header will only represent the number of zone descriptors in the buffer when the partial bit was set to true, always use calloc(), to avoid the chance that someone might copy this code and call spdk_nvme_zns_report_zones() with the partial bit set to false.
