crypto: s390/sha512 - Initialise upper counter to zero for sha384
Initialise the high bit counter to zero in sha384_init.
Also change the state initialisation to use ctx->sha512.state
instead of ctx->state for consistency.
Fixes: 572b5c4682c7 ("crypto: s390/sha512 - Use API partial block handling")
