[libvirt] [PATCH python] Avoid implicit treatment of an arithmetic result as a boolean
Latest GCC versions are unhappy with us treating an integer
arithmetic result as a boolean:
libvirt-utils.c: In function ‘virReallocN’:
libvirt-utils.c:111:23: warning: ‘*’ in boolean context, suggest ‘&&’ instead
[-Wint-in-bool-context]
if (!tmp && (size * count)) {
~~~~~~^~~~~~~~
Add an explicit comparison '!= 0' to keep it happy, since its
suggestion to use '&&' is nonsense.
