crypto: padlock - Fix compile error on i386
The previous change to allow hashing from states other than the initial broke compilation on i386 because the inline assembly tried to squeeze a u64 into a 32-bit register. As we've already checked for 32-bit overflows we can simply truncate it to u32, or unsigned long so that we don't truncate at all on x86-64. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
