When manually initialising a 'struct RSAKey' due to loading an SSH1

public key but not the private half, NULL out all the CRT-optimisation
fields as well as the private exponent pointer. Otherwise segfaults -
security-harmless, but annoying - can happen in freersakey() when we
notice they aren't null and try to free them.
