qemu: allow device block I/O tuning in session mode

Browse Source 
In commit 45ad1adb I added a nicer message for tunings that need
cgroups when unavailable (unprivileged), but I added this check for
I/O tuning of block devices, which doesn't need cgroups, because it is
done by QEMU, so let's fix that.
