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.
