clang on Fedora started to complain about some calls to g_new0() we're making in vbox_snapshot_conf.c. Specifically, we're passing zero as number of elements to allocate. And while usually SA tools are not clever, in this specific case clang is right. There are three cases where such call is made, but all of them later use VIR_EXPAND_N() to allocate more memory (if needed). But VIR_EXPAND_N() accepts a variable set to NULL happily. Therefore, just drop those three calls to g_new0(..., 0) and let VIR_EXPAND_N() allocate memory.
