Fix unused variable warning in iflib.c

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

    sys/net/iflib.c:993:8: error: variable 'n' set but not used [-Werror,-Wunused-but-set-variable]
            u_int n;
                  ^

The 'n' variable appears to have been a debugging aid that has never
been used for anything, so remove it.
