Fix RSA_X931_derive_ex

In the RSA_X931_derive_ex a call to BN_CTX_new is made. This can return
NULL on error. However the return value is not tested until *after* it is
derefed! Also at the top of the function a test is made to ensure that
|rsa| is not NULL. If it is we go to the "err" label. Unfortunately the
error handling code deref's rsa.
