[PATCH for-next 2/2] btrfs: fix double free in btrfs_get_dev_zone_info
When we end up getting an unsupported zone model in btrfs_get_dev_zone_info() the default error handling case frees all allocated resources, but "zones" was already freed resulting in a double-free and "zone_info" is already assigned to device->zone_info resulting in a potential use-after-free. Fo
