[PATCH] Fix build issues with GCC 12's -Werror=address

[Dirk Müller]

GCC 12 is able to detect that if(foo) when foo is a char foo[]
is always true, and hence errors out:

   printerc:336:7: error: the comparison will always evaluate as 'true'
                           for the address of 'response' will never be NULL
   336 |   if (r->response)
       |       ^
   In file included from printer.h:27,
                    from printer.c:28:
   tokens.h:139:8: note: 'response' declared here
   139 |   char response[DIGEST_MD5_RESPONSE_LENGTH + 1];
       |        ^~~~~~~~

We can just remove those conditions.
