mm/damon: document region size validation in damon_set_regions()
The kernel doc comment of damon_region clearly specifies every region
should have positive size. But it is unclear who should verify it.
damon_set_regions() is the recommended DAMON core function for setting
regions from the callers, and has the verification. Update the comment to
clarify the callers should be ok to pass any values for region addresses,
as long as they use damon_set_regions().
