features/bitrot: Fix rescheduling scrub-frequency
While rescheduling scrub frequency, boot time of
the brick was considered where it is not required
and also delta is calculated using unsigned int
resulting in the loss of fractional part leading to
wrong scrub frequency. Boot time is completely
removed and delta calculation is simplified.
