[S390] cio: no path after machine check.
Devices enter no-path state after disabling a channel path via the SE even though another path has been reenabled at the SE. The devices are set into no-path state before triggering path verification even though other paths may have become available. To fix this trigger path verification before setting a device into no-path state.
