The code to fsck an index operates directly on the_index. Let's move it into its own function in preparation for handling the index files from other worktrees.
Since we now have only a single reference to the_index, let's drop our USE_THE_INDEX_VARIABLE definition and just use the_repository.index directly. That's a minor cleanup, but also ensures that we didn't miss any references when moving the code into fsck_index().
