ssh_packet_socket_callback() will not return error codes like
SSH_ERROR on failure. Instead it will always return an unsigned
size_t value representing the number of bytes which have been
processed.
So adjust the assert in the test accordingly, making sure that all
input bytes have actually been processed.
