On Debian 12 Bookworm (and also Proxmox VE 8), the old value '/dev'
cannot be used as the base path, because '/dev/<pool>' will not exist.
If '/dev/zvol' exists, assume that it will contain the usual ZFS
device paths. Only fall back to '/dev' if '/dev/zvol' does not exist
for backwards compatibility.

If other exotic setups pop up where this is not enough, it can still
be made into an actual storage configuration property. From the
existing reports, this should be enough however and the logic makes
sense as the default behavior even if we later add it as a storage
configuration property. Of course then we can use an on_add() hook,
only check the existence once and write the result to the config.
I can also go with that approach right away if we deem the breakage
potential for existing exotic setups where /dev/zvol exists, but is
not valid as the base path, too high.
