[OpenIndiana-discuss] force ZFS to update disk quota info

[CJ Keist]

Here are actual numbers:

# du -sh *
   11G   home

zfs list data/students/GRAD/ECE/vwb
NAME                         USED  AVAIL  REFER  MOUNTPOINT
data/students/GRAD/ECE/vwb  13.6G  6.37G  13.6G  /data/students/GRAD/ECE/vwb

As you can see there is about 3Gb difference in what du reports and what 
ZFS reports.  I bumped up his quota so that he could work.
It's been days since this was done and ZFS is not change the disk usage.

zfs list -o space data/students/GRAD/ECE/vwb
NAME                        AVAIL   USED  USEDSNAP  USEDDS 
USEDREFRESERV  USEDCHILD
data/students/GRAD/ECE/vwb  6.37G  13.6G         0       0
