pstore: constify pstore_zbackend structures
The references of pstore_zbackend structures are stored into the pointer zbackend of type struct pstore_zbackend. The pointer zbackend can be made const as it is only dereferenced. After making this change the pstore_zbackend structures whose references are stored into the pointer zbackend can be made const too.
