We don't tear down the minor until the final put_disk, fixing the
major/minor lifetime issue. That was commit:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2da78092dda13f1efd26edbbf99a567776913750
The namespace's disk_name using the IDA is released in the same path as
the final put_disk, so I think we're safe.
