[Qemu-devel] [PATCH v3] pci: Set err to errp directly rather than through error_propagate() |

ioh3420_interrupts_init() and its callers rp_realize() fill error
message to local_err, then propagate it to errp by error_propagate(),
which is not necessary. So eliminate it and pass errp directly instead
of local_err. Of course, error_propagate() also has been removed.
