readdcw: close handle during unwatch state

The Unwatch method on Windows is asynchronous. Thus, when calling Watch, Unwatch and Watch on the same path, the Unwatch state may happen after the second Watch call. This means that second Watch will be skipped as already created.

This commit makes second Watch call invalidate Unwatch state. So Watch->Unwatch->Watch calls will be basically a no-op. This doesn't solve all the problems since the second Watch might have different events to handle. However, the implementation should use Rewatch method instead.

Also, the code fixes a data race that may occur when invalidating grip handle.

Fixes: #150
