Suppress unused variable warning in if_malo.c
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. MFC after: 3 days
