PCI_CAP_EXP_ENDPOINT_SIZEOF_V1 defines the size of the PCIe capability structure for v1 devices with link, but we also have a need in the vfio code for sizing the capability for devices without link, such as Root Complex Integrated Endpoints. Create a separate define for this ending the structure before the link fields. Additionally, this reveals that PCI_CAP_EXP_ENDPOINT_SIZEOF_V2 is currently incorrect, ending the capability length before the v2 link fields. Rename this to specify an RC Integrated Endpoint (no link) capability length and move PCI_CAP_EXP_ENDPOINT_SIZEOF_V2 to include the link fields as we have for the v1 version.
