dsched_fq - Avoid int64 overflow on total_budget
* Avoid an int64 overflow when calculating the total disk budget by
losing bits of precision if needed.
* Note that this might not quite fix the issue yet, as there is one
other place where the int64 overflow can happen, although it is less
likely.
* While here, make the rebalancing happen every 0.5s instead of every
1s, effectively reducing the chance of int64 overflows.
