vfio: selftests: Expose more vfio_pci_device functions
Refactor and make the functions called under device initialization
public. A later patch adds a test that calls these functions to validate
the UAPI of SR-IOV devices. Opportunistically, to test the success
and failure cases of the UAPI, split the functions dealing with
VFIO_GROUP_GET_DEVICE_FD and VFIO_DEVICE_BIND_IOMMUFD into a core
function and another one that asserts the ioctl. The former will be
used for testing the SR-IOV UAPI, hence only export these.
