From: Eric Biggers <ebiggers@xxxxxxxxxx> In the Linux kernel, a function whose name has two leading underscores is conventionally called by the same-named function without leading underscores -- not the other way around. __sha2_ce_transform() and __sha256_block_data_order() got this backwards. Fix this, albeit without changing "sha256_block_data_order" in the perlasm since that is OpenSSL code. No change in behavior.
