hw: Fix error API violation around object_property_set_link()
The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. virtio_gpu_pci_base_realize(), virtio_vga_base_realize(), sparc32_ledma_device_realize(), sparc32_dma_realize(), sparc32_dma_realize() xilinx_axidma_realize(), mips_cps_realize(), macio_realize_ide(), xilinx_enet_realize(), and virtio_iommu_pci_realize() are wrong that way: they reuse the argument they pass to object_property_set_link() for another call. Harmless, because object_property_set_link() can't actually fail for them: it fails when the property doesn't exist, is not settable, or its .check() method fails. Fix by passing &error_abort instead. Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Cc: "Edgar E.
