Guenter Roeck b5319c9629 Revert "sh: Handle calling csum_partial with misaligned data" 
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.

    # Subtest: checksum
