arm64/crypto: remove redundant update of data

Originally found by cppcheck:

[arch/arm64/crypto/sha2-ce-glue.c:153]: (warning) Assignment of
function parameter has no effect outside the function. Did you
forget dereferencing it?

Updating data by blocks * SHA256_BLOCK_SIZE at the end of
sha2_finup is redundant code and can be removed.
