sysctl: don't print negative flag for proc_douintvec
I saw some very confusing sysctl output on my system: # cat /proc/sys/net/core/xfrm_aevent_rseqth -2 # cat /proc/sys/net/core/xfrm_aevent_etime -10 # cat /proc/sys/net/ipv4/tcp_notsent_lowat -4294967295 Because we forget to set the *negp flag in proc_douintvec, so it will become a garbage value. Since the value related to proc_douintvec is always an unsigned integer, so we can set *negp to false explictily to fix this issue.
