[PATCH 03/18] mingw: drop the separate `do_lstat()` function

["Karsten Blees via GitGitGadget" <gitgitgadget@gmail.com>]

From: Karsten Blees <blees@dcon.de>

With the new `mingw_stat()` implementation, `do_lstat()` is only called
from `mingw_lstat()` (with the function parameter `follow == 0`). Remove
the extra function and the old `mingw_stat()`-specific (`follow == 1`)
logic.
