[DCCP]: Shorten variable names in dccp_check_seqno

This patch is in part required by the next patch; it

* replaces 6 instances of DCCP_SKB_CB(skb)->dccpd_seq' with seqno';
* replaces 7 instances of DCCP_SKB_CB(skb)->dccpd_ack_seq' with ackno';
* replaces 1 use of dccp_inc_seqno() by unfolding `ADD48' macro in place.

No changes in algorithm, all changes are text replacement/substitution.

I think this would be better served by a macro e.g. #define SEQNO DCCP_SKB_CB(skb)->dccpd_seq

With the change you're making here you're increasing stack usage by 16 bytes.
