net: dccp: fix sign bug

'gap' is unsigned, so this code is wrong:

    gap = -new_head;
    ...
    if (gap > 0) { ... }

Make 'gap' signed.

The semantic patch that finds this problem (many false-positive results):

// <smpl>

identifier f;

int f(...) { ... }

@@
identifier r1.f;

unsigned T x;

*x = f(...)
 ...
*x > 0
