[PATCH] crypto: scatterwalk - Use sg_chain_ptr on chain entries

[Tom Lendacky <thomas.lendacky@amd.com>]

Now that scatterwalk_sg_chain sets the chain pointer bit the sg_page
call in scatterwalk_sg_next hits a BUG_ON when CONFIG_DEBUG_SG is
enabled. Use sg_chain_ptr instead of sg_page on a chain entry.
