Sasha Levin e2cfa7b093 Revert "swiotlb: fix info leak with DMA_FROM_DEVICE" ...

This reverts commit d4d975e792.

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.
