[PATCH v2 01/29] diff.c: remove redundant canon_mode() call

Remove a call to canon_mode() from fill_filespec(). This has been
redundant since the tree-walk.c API supplies it pre-canonicalized
since 7146e66f086 (tree-walk: finally switch over tree descriptors to
contain a pre-parsed entry, 2014-02-06).

This call to the predecessor of canon_mode() was added back in
4130b995719 ([PATCH] Diff updates to express type changes,
2005-05-26).

This was the only such call in the codebase. The rest are all either
one of these sorts of forms:

    canon_mode(st.st_mode); /* a stat(2) struct */
    canon_mode(S_IFREG | 0644) /* A compile-time literal */
