Subject: Revert "qemu: emit error when trying to update blkiotune group_name in qemuDomainChangeDiskLive"


https://bugzilla.redhat.com/show_bug.cgi?id=1601677

This reverts commit 047cfb05ee949325e77726531fd381820be8dc62
Using numeric comparison on strings means we reject every update
that does include the group name, even if it's unchanged.
