[libvirt] [PATCH] qemu: avoid 32-bit compiler warning

[Eric Blake]

On 32-bit platforms, gcc warns that the comparison between a long
and (ULLONG_MAX/1024/1024) is always false; throwing in a type
conversion shuts up the warning.

* src/qemu/qemu_monitor.c (qemuMonitorBlockJob): Shut gcc up.

Pushing under the build-breaker rule.
