Revert "sh: Handle calling csum_partial with misaligned data"
[ Upstream commit b5319c96292ff877f6b58d349acf0a9dc8d3b454 ]
This reverts commit cadc4e1a2b.
Commit cadc4e1a2b ("sh: Handle calling csum_partial with misaligned
data") causes bad checksum calculations on unaligned data. Reverting
it fixes the problem.
