Subject: [PATCH] vim-patch:8.2.4283: using a variable for the return value is
 not needed

Problem:    Using a variable for the return value is not needed.
Solution:   Return the value directly. (closes vim/vim#9687)
https://github.com/vim/vim/commit/73257149d759a8e6ddbe555d2b5aa37b6cb8db8b

Also move down variable declarations in changedir_func().
vim_chdirfile() doesn't need change.
