[libvirt] [PATCH 2/3] qemu: Ignore subsequent attempts to probe device properties

[Andrea Bolognani]

In some cases, we are probing multiple devices for the same
property and setting the corresponding capability if it's
found on any of the devices: when that happens, we can quit
early after finding the first property and avoiding a bunch
of string comparisons.
