netfilter: conntrack: convert sysctls to u8
log_invalid sysctl allows values of 0 to 255 inclusive so we no longer need a range check: the min/max values can be removed. This also removes all member variables that were moved to net_generic data in previous patches. This reduces size of netns_ct struct by one cache line.
