crypto: rng - Mark crypto_rng_reset seed as const
There is no reason why crypto_rng_reset should modify the seed so this patch marks it as const. Since our algorithms don't export a const seed function yet we have to go through some contortions for now. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
