Documentation: block: zloop: clarify capacity alignment

zloop divides the requested capacity by the zone size to determine the
number of zones. Since it uses one zone size for all zones, a smaller last
zone is not supported and an unaligned capacity is rounded down.

The capacity_mb description incorrectly states that the capacity is rounded
up. Correct it to document the actual behavior.
