conf: Fix out-of-bounds write during cleanup of virDomainNumaDefNodeDistanceParseXML mem_nodes[i].ndistances is written outside the loop causing an out-of-bounds write leading to heap corruption. While we are at it, the entire cleanup portion can be removed as it can be handled in virDomainNumaFree. One instance of VIR_FREE is also removed and replaced with g_autofree. This patch also adds a testcase which would be picked up by ASAN, if this portion regresses.
