cifs: add fallback in is_path_accessible for old servers

commit 221d1d797202984cb874e3ed9f1388593d34ee22 upstream.

The is_path_accessible check uses a QPathInfo call, which isn't
supported by ancient win9x era servers. Fall back to an older
SMBQueryInfo call if it fails with the magic error codes.
