Suppress unused variable warning in ip_dummynet.c

With clang 15, the following -Werror warning is produced:

    sys/netpfil/ipfw/ip_dummynet.c:802:6: error: variable 'n' set but not used [-Werror,-Wunused-but-set-variable]
            int n = 0; /* only for stats */
                ^

Here, 'n' is a variable that is only used when debugging. Mark the
variable as potentially unused, to suppress the warning.
