    Suppress unused variable warning in if_mwl.c
    
    With clang 15, the following -Werror warning is produced:
    
        sys/dev/mwl/if_mwl.c:3445:8: 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 debugging. Mark the
    variable as potentially unused, to suppress the warning.
    
    MFC after:      3 days
    
    (cherry picked from commit 52c80d495a1b9dc756452ebcbb945906ea3cf23a)
