[S390] lost interrupt after chpid vary off/on cycle.
I/O on a CCW device may stall if a channel path to that device is logicaly varied off/on. A user I/O interrupt can get misinterpreted as interrupt for an internal path verification operation due to a missing check and is therefore never reported to the device driver. Correct check for pending interruptions before starting path verification.
