Suppress unused variable warning in if_malo.c

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

    sys/dev/malo/if_malo.c:1573:8: error: variable 'ix' set but not used [-Werror,-Wunused-but-set-variable]
            u_int ix;
                  ^

Here, 'ix' is a variable that is only used when MALO_DEBUG is defined.
Mark the variable as potentially unused, to suppress the warning.
