Elena Petrova 6bd934de1e crypto: arm64/sha2-ce - correct digest for empty data in finup
The sha256-ce finup implementation for ARM64 produces wrong digest
for empty input (len=0). Expected: the actual digest, result: initial
value of SHA internal state. The error is in sha256_ce_finup:
for empty data `finalize` will be 1, so the code is relying on
sha2_ce_transform to make the final round. However, in
sha256_base_do_update, the block function will not be called when
len == 0.

Fix it by setting finalize to 0 if data is empty.

Fixes: 03802f6a80 ("crypto: arm64/sha2-ce - move SHA-224/256 ARMv8 implementation to base layer")
