ec: Fix return errors when not enough bricks
Changes introduced by this patch: * Fix an incorrect error propagation when the state of the life cycle of a fop returns an error. * Fix incorrect unlocking of failed locks. * Return ENOTCONN if there aren't enough bricks online. * In readdir(p) check that the fd has been successfully open by a previous opendir.
