[PATCH v2 0/3] MR5737: Draft: kernelbase: Use ERROR_DIRECTORY for FindFirstFileExW on invalid name.

[Brendan McGrath (＠redmcg)]

When `FindFirstFileA` is called with `<path>/<file>/*` (where file is expected to be a directory), Windows uses the `ERROR_DIRECTORY` error.

This patch changes Wine's implementation to match Windows. This fixes a crash in Unity of Command II.
