[libvirt] [PATCH] build: Fix build warning on libvirt-python

From: Mo Yuxiang <Moyuxiang(a)huawei.com&gt; On compiling libvirt-python, we get such a warning: libvirt-qemu-override.c: In function ‘libvirt_qemu_virConnectDomainQemuMonitorEventRegister’: libvirt-qemu-override.c:304: warning: suggest explicit braces to avoid ambiguous ‘else’ Py_DECREF is a macro. The solution is to add brackets.
