res_counter: fix off-by-one bug in setting limit
I found we can no longer set limit to 0 with 2.6.27-rcX:
# mount -t cgroup -omemory xxx /mnt
# mkdir /mnt/0
# echo 0 > /mnt/0/memory.limit_in_bytes
bash: echo: write error: Device or resource busy
It turned out 'limit' can't be set to 'usage', which is wrong IMO.
