build: avoid compiler warning

gcc 4.1.2 on RHEL 5 warned:
conf/network_conf.c:3136: warning: 'foundIdx' may be used uninitialized in this function

The warning is spurious, but initializing the variable doesn't hurt.

* src/conf/network_conf.c (virNetworkDefUpdateDNSHost): Silence
unused variable warning.
