Btrfs: allow for selecting only completely empty chunks

Browse source

Enhance balance usage filter by making it possible to balance out only
completely empty chunks.  Today, usage filter properly acts on values
from 1 to 99 inclusive, usage=100 selects all chunks, and usage=0
selects no chunks.  This commit changes the usage=0 case: the new
meaning is to restripe only completely empty chunks and nothing else.
