We've resolved this in fstests with canonicalizing device symlinks, and
through kdevops its possible to even use PCIe passthrough onto a guest
using dynamic kconfig (ie, specific to the host).

It should be possible to do that in blktests too, but the dynamic
kconfig thing is outside of scope, but this is a long winded way of
suggestin that if we extend blktests to add a canonon-similar device
function, then since kdevops supports blktests you get that pcie
passthrough for free too.
