  Changed paths:
    M crypto/rsa/rsa_gen.c
    M test/rsa_mp_test.c

  Log Message:
  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().
