[libvirt] [PATCH] Resolve Coverity issue regarding not checking return value

Coverity complains that the call to virPCIDeviceDetach() in qemuPrepareHostdevPCIDevices() doesn't check status return like other calls. Seems this just was lurking until a recent change to this module resulted in Coverity looking harder and finding the issue. Introduced by 'a4efb2e33' when function was called 'pciReAttachDevice()' Just added a ignore_value() since it doesn't appear to matter if the call fails since we're on a failure path already.
