Subject: [PATCH] qemuDomainGetVcpusFlags: Initialize ncpuinfo

https://bugzilla.redhat.com/show_bug.cgi?id=924400

Currently, there's a path to use the ncpuinfo variable uninitialized,
which leads to a compiler warning:

    qemu/qemu_driver.c: In function 'qemuDomainGetVcpusFlags':
    qemu/qemu_driver.c:4573:9: error: 'ncpuinfo' may be used
    uninitialized in this function [-Werror=maybe-uninitialized]
             for (i = 0; i < ncpuinfo; i++) {
             ^
