Sasha Levin e2cfa7b093 Revert "swiotlb: fix info leak with DMA_FROM_DEVICE"
This reverts commit d4d975e7921079f877f828099bb8260af335508f.

Upstream had a follow-up fix, revert, and a semi-reverted-revert.
Instead of going through this chain which is more painful to backport,
I'm just going to revert this original commit and pick the final one.
