Niklas Schnelle dda9cc82e5 s390/pci: Do not try re-enabling load/store if device is disabled
commit b97a7972b1 upstream.

If a device is disabled unblocking load/store on its own is not useful
as a full re-enable of the function is necessary anyway. Note that SCLP
Write Event Data Action Qualifier 0 (Reset) leaves the device disabled
and triggers this case unless the driver already requests a reset.
