[patch] s390: dasd set offline kernel bug.

[Martin Schwidefsky]

From: Horst Hummel <horst.hummel@xxxxxxxxxx>

[S390] dasd set offline kernel bug.

The request queue flush function of the dasd driver has to dequeue
the requests first and then call the end request function. Otherwise
a kernel bug in ll_rw_block.c might get triggered.
