time: settimeofday: Validate the values of tv from user
commit 6ada1fc0e1c4775de0e043e1bd3ae9d065491aa5 upstream.
An unvalidated user input is multiplied by a constant, which can result in
an undefined behaviour for large values. While this is validated later,
we should avoid triggering undefined behaviour.
