[PATCH] xfs/649: don't override $SCRATCH_DEV

[Christoph Hellwig <hch@lst.de>]

xfs/649 operates on a scsi_debug device.  Don't try to shoe-horn it
into $SCRATCH_DEV a that causes problems for setups that don't test
a SCRATCH_DEV at all, or which use options for the scratch device that
don't apply to the scsi debug device.
