The NCP (data channel crypto negotiation) code on the client side waits
for an incoming PUSH_REPLY before setting up the data channel crypto
parameters, because the PUSH_REPLY could contain a "cipher xxx" setting.

In the particular case of a empty PUSH_REPLY message, the relevant code
bits was not called because "we have not received any options, do not
bother to look into it in more detail" - so, ciphers were not set up,
resulting in an error message like this:

    Key [AF_INET]... [0] not initialized (yet), dropping packet.

Remove that check, always init the crypto layer on PUSH_REPLY.
