[Zdenek Kabelac]

> It's not clear how this code is supposed to work.
> For now we never set INCONSISTENT_VG flag - so marking expression with
> big FIXME as it always gives true.
> Remove extra paramater from lvmcache_update_vg call - as it effectively
> produced always 'false' - so reverting to previous version - where it has been
> possible to get also 'true' - use case is probably only in cluster
> environment - some testcase is needed.
