drbd: drbd_send_ack_dp must not rely on header information

drbd commit 17c854fea474a5eb3cfa12e4fb019e46debbc4ec
drbd: receiving of big packets, for payloads between 64kByte and 4GByte
introduced a new on-the-wire packet header format.  We must no longer
assume either format, but use the result of whatever drbd_recv_header
has decoded.
