xio3130_downstream: Report error if pcie_chassis_add_slot() failed

On commit f8cd1b02 ("pci: Convert to realize"), no error_set*()
call was added for the pcie_chassis_add_slot() error case.
pcie_chassis_add_slot() errors get ignored, making QEMU crash
later.  e.g.:

  $ qemu-system-x86_64 -device ioh3420 -device xio3130-downstream
  qemu-system-x86_64: memory.c:2166: memory_region_del_subregion: Assertion `subregion->container == mr' failed.
  Aborted (core dumped)

Fix it by reporting the error using error_setg().
