FIXES 60258

When the ACL on a directory is list only, attempts to read the status
of items in the directory will fail.  Therefore, it is pointless to try.
Instead, when we know the user ACL does not have read permission, we
should immediately lie about the status info.  That way we don't pound
the file server with requests that will produce an abort which in turn
will trigger force the file server to delay responses to the client.

This change has the added benefit that cached status info is no longer
leaked to callers that do not have appropriate permissions.

With this change the Explorer Shell is much more responsive.
