tcp: Add TCP_USER_TIMEOUT negative value check
TCP_USER_TIMEOUT is a TCP level socket option that takes an unsigned int. But patch "tcp: Add TCP_USER_TIMEOUT socket option"(dca43c75 ) didn't check the negative values. If a user assign -1 to it, the socket will set successfully and wait for 4294967295 miliseconds. This patch add a negative value check to avoid this issue.
