Hannes Reinecke e3bde04f1e dm mpath: reduce memory pressure when requeuing 
When multipath needs to requeue I/O in the block layer the per-request
context shouldn't be allocated, as it will be freed immediately
afterwards anyway.  Avoiding this memory allocation will reduce memory
pressure during requeuing.
