s390/dasd: fix hanging blockdevice after request requeue

Browse source 
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.
