    netfilter: xt_rateest: fix comparison with self
    
    As noticed by Török Edwin <edwintorok@xxxxxxxxx>:
    
    Compiling the kernel with clang has shown this warning:
    
    net/netfilter/xt_rateest.c:69:16: warning: self-comparison always results in a
    constant value
                            ret &= pps2 == pps2;
                                        ^
    Looking at the code:
    if (info->flags & XT_RATEEST_MATCH_BPS)
                ret &= bps1 == bps2;
            if (info->flags & XT_RATEEST_MATCH_PPS)
                ret &= pps2 == pps2;
    
    Judging from the MATCH_BPS case it seems to be a typo, with the intention of
    comparing pps1 with pps2.
