slontis 7efc653c43 Make RSA_generate_multi_prime_key() not segfault if e is NULL. 
This is not a big problem for higher level keygen, as these set e
beforehand to a default value. But the logic at the lower level is
incorrect since it was doing a NULL check in one place but then
segfaulting during a later BN_copy().
