libcacard/vreader: Drop broken recovery from failed assertion

We suppress some code when we got unexpected status and assertion
checking is off:

     assert(card_status == VCARD_DONE);
     if (card_status == VCARD_DONE) {
         int size = MIN(*receive_buf_len, response->b_total_len);
         memcpy(receive_buf, response->b_data, size);
         *receive_buf_len = size;
    }

Such "recovery" is of dubious value even when it works.  This one
doesn't: it fails to assign to receive_buf[] and *receive_buf_len,
which the callers expect.

Make the code unconditional.
