pci: hotplug bridge fixes

Hi,

While testing pci bridge hotplug via device_add, I ran into a couple of qemu segfaults.

The first one was caused by having a refcount greater than 0, in the object_delete() path. Once, I got past that error, I hit a second segfault due to the fact that pci_bridge_dev_initfn() didn't fully cleanup its state.

Thanks,

-Jason
