build: avoid uninitialized use warning

             for (i = 0; i < *cnt; i++) {
                             ^

         size_t i, *cnt;
                    ^
../../src/conf/domain_conf.c:2794:30: error: ‘arrPtr’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
         virDomainChrDefPtr **arrPtr;
                              ^

* src/conf/domain_conf.c (virDomainChrGetDomainPtrs): Always
