Increase buffer size for nvlist for large configurations 

It's still not clear to me why the default value here is large
enough Solaris.  I hit this limit again when setting up 120 SATA
drives configured as 15 raidz2 groups each containing 8 drives.
We expect to go bigger so we may just want to spend a little
time and figure out how to make this all dynamic.
