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

[Wang Rui]

From: Mo Yuxiang <Moyuxiang at huawei.com>

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.
