[Qemu-devel] [PATCH RFC for-1.6 qom-next 1/3] pcie: Move AER log into VMSTATE_PCIE_DEVICE()

[Andreas Färber]

VMSTATE_PCIE_DEVICE() currently has the following users:
* ioh3420
* xio3130-downstream
* x3130-upstream
* nec-usb-xhci

All except for XHCI have VMSTATE_STRUCT(....exp.aer_log, ...) following
VMSTATE_PCIE_DEVICE(), and XHCI was marked unmigratable in v1.5.0.

Therefore move this recurring PCIe-only field into vmstate_pcie_device
while we still can without breaking migration compatibility.
