git-reset: do not be confused if there is nothing to reset
The purpose of the function update_index_from_diff() (which is the
callback function we give do_diff_cache()) is to update those index
entries which differ from the given commit.
Since do_diff_cache() plays games with the in-memory index, this function
discarded the cache and reread it.
Then, back in the function read_from_tree() we wrote the index.
Of course, this broke down when there were no changes and
update_index_from_diff() was not called, and therefore the mangled index
was not discarded.
The solution is to move the index writing into the function
update_index_from_diff().
Noticed by Björn Steinbrink.
