Safes a lot of argument passing to a function that is used
only once.

- * @param state_name Name of the state
- * @param of_path Path in the devicetree
- * @param stridesize stridesize in case we have a medium without eraseblocks.
- * stridesize describes how far apart copies of the same data should be stored.

- * @param storagetype Type of the storage backend. This may be NULL where we
- * autoselect some backwardscompatible backend options
- * @return 0 on success, -errno otherwise
