Liping Zhang 7bdacd3d9f sysctl: report EINVAL if value is larger than UINT_MAX for proc_douintvec
commit 425fffd886bae3d127a08fa6a17f2e31e24ed7ff upstream.

Currently, inputting the following command will succeed but actually the
value will be truncated:

  # echo 0x12ffffffff > /proc/sys/net/ipv4/tcp_notsent_lowat

This is not friendly to the user, so instead, we should report error
when the value is larger than UINT_MAX.

Fixes: e7d316a02f ("sysctl: handle error writing UINT_MAX to u32 fields")
