dcrypto/hmac: another fix for HMAC SHA256 compute
For long HMAC keys we should also compare length with SHA256 block size
rather than size of opad. It updates previous patch.
https://crrev.com/c/1850535 introduced change in LITE_HMAC_CTX structure
which change size of opad field. HMAC computation was using sizeof(opad)
instead of SHA256_BLOCK_SIZE and that caused incorrect values.
