lib-index: Fix dangling index->map pointer when fsck fails in mail_index_map_latest_file()

If mail_index_fsck() returns -1 (e.g. log lock failure), index->map was
left pointing at new_map. The subsequent mail_index_unmap(&new_map) freed
that object, leaving index->map as a dangling pointer.

Fix by restoring index->map = old_map before breaking on fsck error,
mirroring what the success path already does.
