[patch 31/32] [PATCH] dasd: correct offline processing

[Martin Schwidefsky]

From: Stefan Haberland <stefan.haberland@xxxxxxxxxx>

Flushing the dasd ccw request queue may stop the processing of the
block device request queue. Destroy partitions may wait for
outstanding requests and thus hang. 
Swapping dasd_destroy_partitions and dasd_flush_request_queue so that
the request queue is empty before dasd_destroy_partitions is called.
