Clear search state variables in rsa.c's find_prime().
Failing to clear the temporary buffer used to transfer bits from the TRNG into a bignum was a real leak of something very close to keying material, albeit only onto the local stack where it was almost certain to have been overwritten by subsequent operations (generation of other key components, wrap and PKCS #8 encoding) before pkey_generate_rsa() ever returned to its caller. Still, bad coder, no biscuit. Failing to clear the remainders array was probably harmless, but doctrine says clear it anyway.
