tc: gred: fix debug print

When build with -DDEBUG, tc build fails with:
q_gred.c: In function ‘init_gred’:
q_gred.c:53:17: error: passing argument 2 of ‘fprintf’ from incompatible pointer type [-Wincompatible-pointer-types]
   53 |                 DPRINTF(stderr, "init_gred: invoked with %s\n", *argv);
      |                 ^~~~~~~
      |                 |
      |                 FILE *

This is due to the DPRINTF macro call. Indeed DPRINTF is defined as a
two-args macro when -DDEBUG is used, while it uses 3 args in this call.

Fix it simply dropping the useless first arg.
