[PATCH 1/1] dccp: re-enable debug macro

[Gerrit Renker <gerrit@erg.abdn.ac.uk>]

dccp tfrc: revert

This reverts 6aee49c558de (Jan 4, 2014) since the variable tfrc_debug is
referenced by the tfrc_pr_debug(fmt, ...) macro when TFRC debugging is
enabled. If it is enabled, use of the macro produces a compilation error.
