Sasha Levin 7336dcc213 time: settimeofday: Validate the values of tv from user ...

commit 6ada1fc0e1 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.
