The test created ZFS datasets with canmount=noauto, but pam_zfs_key's
mount_dataset() now checks canmount == ZFS_CANMOUNT_ON and skips
mounting otherwise (added in
https://github.com/openzfs/zfs/commit/387ed5ca41). Use the default
canmount=on and unmount before unloading the key to compensate for
the auto-mount that happens when the key is loaded during creation.
This also silences the warning for forceImportRoot.
