Fix block incremental restore issue on non-default repository.

If the selected backup to restore was not in the default (lowest number) repository and block incremental was used, then restore would erroneously try to load the file super block list from the default repository. Specifying --repo would fix this since it changed the default repository.

Fix by updating the super block read to the specified repository.
