[libvirt] [PATCH] build: avoid older gcc warning
Jim Fehlig reported a compilation error with older gcc 4.3.4:
libvirt.c: In function 'virDomainGetEmulatorPinInfo':
libvirt.c:9111: error: logical '&&' with non-zero constant will always
evaluate as true [-Wlogical-op]
It looks like someone programmed via too much copy-and-paste.
* src/libvirt.c (virDomainGetEmulatorPinInfo): Multiplying by 1 is
a no-op, and thus will never overflow.

Pushing under the build-breaker rule.
