thin: fix percentage compare

Browse Source 
Since plugin's percentage compare has been fixed,
it's now revealed wrong compare here.

The logic for threshold is - to allow to go as high
as given value e.g. 80% - so if pool is exactlu 80%
full it's still allowed to use it (dmeventd will not
resize it).
