If the /etc/fstab of a guest contains devices specified with UUID or
LABEL, then the new OCaml inspection code will report the findfs failure
as general failure of the inspection. OTOH, the old C inspection code
simply ignored all the devices that cannot be resolved.
Hence, restore the old behaviour by ignoring unresolvable devices.
