Stefan Haberland 08bccd7212 s390/dasd: fix hanging IO request during DASD driver unbind ...

commit 66f669a272 upstream.

Prevent that an IO request is build during device shutdown initiated by
a driver unbind. This request will never be able to be processed or
canceled and will hang forever. This will lead also to a hanging unbind.

Fix by checking not only if the device is in READY state but also check
that there is no device offline initiated before building a new IO request.
