ipv4: make tcp_notsent_lowat sysctl knob behave as true unsigned int
[ Upstream commit b007f09072ca8afa118ade333e717ba443e8d807 ]
> cat /proc/sys/net/ipv4/tcp_notsent_lowat
-1
> echo 4294967295 > /proc/sys/net/ipv4/tcp_notsent_lowat
-bash: echo: write error: Invalid argument
> echo -2147483648 > /proc/sys/net/ipv4/tcp_notsent_lowat
> cat /proc/sys/net/ipv4/tcp_notsent_lowat
-2147483648
but in documentation we have "tcp_notsent_lowat - UNSIGNED INTEGER"
v2: simplify to just proc_douintvec
