chfs is a unidirectional command, ie, you can increase but not decrease a
filesystem. To do what you want, try the following:

0. figure out how large you really want /usr to be remembering that it's
   very easy to increase it later
1. backup /usr
2. remove /usr -> you have to do this in maintainence mode
3. remake /usr with a smaller size
4. restore /usr

You can do most of these steps in smit. Good luck.
