common, osd: add sanity checks around osd_scrub_max_preemptions

to limit maximum preempt_divisor we can use when backing off the
chunky-scrub range on preempting.

Otherwise large osd_scrub_max_preemptions values (i.e., >= 32)
would cause preempt_divisor overflow, hence the dreaded
“divide by zero error”.
