[PATCH] mingw_rmdir: do not prompt for retry when non-empty

[Erik Faye-Lund <kusmabite@gmail.com>]

in ab1a11be ("mingw_rmdir: set errno=ENOTEMPTY when appropriate"),
a check was added to prevent us from retrying to delete a directory
that is both in use and non-empty.

However, this logic was slightly flawed; since we didn't return
immediately, we end up falling out of the retry-loop, but right into
the prompting loop.

Fix this by simply returning from the function instead of breaking
the loop.

While we're at it, change the second break to a return as well; we
already know that we won't enter the prompting-loop, beacuse
is_file_in_use_error(GetLastError()) already evaluated to false.

Here's a quick patch for a small issue I recently encountered; when
deleting a file from inside a directory, we currently end up
prompting the user if (s)he want us to retry deleting the directory
they are in.
