fixed zone instance name

[barryiron]

Fixes problem where the incorrect instance-name is set.

zone in my setup is set to crc and numZoneInstances to 2

Instance number 0 is always called default, however it should be called crc-inst0.

Before fix:

The change looks good. However, loxilb has some dependency on "default" instance name hence the reason for the check in the first place. But nonetheless, planning to take care of the these hard coded dependencies in loxilb.
