Subject: [PATCH v4 1/3] net/xen-netfront: Correct printf format in xennet_get_responses

rx->status is an int16_t, print it using %d rather than %u in order to
have a meaningful value when the field is negative.

Also use %u rather than %x for rx->offset.

    Changes in v4:
        - Use %u for the rx->offset because offset is unsigned

    Changes in v3:
        - Use %d for the rx->offset too.

    Changes in v2:
        - Add David's Reviewed-by
