Hmm, good point.  I actually already reverted it in svn...

...but now I'm not sure it's worth worrying about.  The only
problematic arch (x86_64 with GART IOMMU) will not ever use the IOMMU
and coalesce sg lists if the device being mapped for can do 64-bit
DMA.  So this bug could never have a practical effect for us.
