Guenter Roeck 019ae041a5 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.
