Stefan Haberland 39c49d310e s390/dasd: fix hanging blockdevice after request requeue
commit d8898ee50e upstream.

The DASD driver does not kick the requeue list when requeuing IO requests
to the blocklayer. This might lead to hanging blockdevice when there is
no other trigger for this.

Fix by automatically kick the requeue list when requeuing DASD requests
to the blocklayer.
