[libvirt] [PATCH] qemu: allow device block I/O tuning in session mode

In commit 45ad1adb I added a nicer message for tunings that need cgroups when unavailable (unprigileged) ,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.

ACK. Peter P.S: Unfortunately the brown box of shame was destroyed recently so you don't have to wear it :)
