    Fix unused variable warning in netipsec's key_debug.c
    
    With clang 15, the following -Werror warning is produced:
    
        sys/netipsec/key_debug.c:923:9: error: variable 'j' set but not used [-Werror,-Wunused-but-set-variable]
                int i, j;
                       ^
    
    The 'j' variable was in key_debug.c when it was first added, but it
    appears to have been a debugging aid that has never been used, so remove
    it.
    
    MFC after:      3 days
    
    (cherry picked from commit c01fdd7a9f316c8c04786441ca0113be002b96be)
