domain_conf.c: Initialize arrVar and cntVar
domain_conf.c: Initialize arrVar and cntVar

Some ancient gcc fails to see the variables are initialized in a
separate function and a false positive is produced:

cc1: warnings being treated as errors

conf/domain_conf.c:10342: error: 'arrVar' may be used uninitialized in this function [-Wuninitialized]
