Nope, did you try
without devices in VM.
2. add check for all aer devices if conflict the topology at each
initfn time.

pcie_aer_init was used to emulate an aer capability for pcie device,
but for vfio device, the aer config space size is mutable and is not
always equal to PCI_ERR_SIZEOF(0x48). it depends on where the TLP Prefix
register required, so here we add a size argument.

For vfio pcie device, we could expose the extended capability on
PCIE bus. in order to avoid config space broken, we introduce
a copy config for parsing extended caps. and rebuild the pcie
extended config space.
