zfs: recognize zpools formatted with features support

Currently no features are implemented, only the zpool version 5000 that
indicating the features support, is recognized. Since it is possible for
OpenZFS to create a pool with features support enabled, but without
enabling any actual feature, this change enables U-Boot to read such
pools.
