commit 9173ae5f7f02d2f1675d505ee3da7e62cceeafd0
Author: David Disseldorp <ddiss at samba.org>
Date:   Tue Sep 3 15:26:19 2019 +0200

    s3/lib/ctdbd_conn: assert hdr following read/recv
    
    ctdb_pkt_recv_recv() and ctdb_read_packet() give us a non-null hdr on
    success, so drop the error path check in favour of an assert.
    
    This fixes a regression in 3913b9a4088b83d6ed7f94d136a26ecfa7e16b35,
    where tevent_req_error() may be skipped in the ctdbd_parse_done()
    ctdb_pkt_recv_recv() error path.
