flowprobe: Fixed assert error with less than 1 second passive timer

When passive timer has less than 1 second left, it'll be forcifully changed to 0 when converting from f64 to u64. As a result the assertion will fail at the beginning of the passive timer start fuction. This commit fixed this bug by adding a check of the delta.
