vfio: selftests: Add helpers to alloc/free vfio_pci_device

Add a helper, vfio_pci_device_alloc(), to allocate 'struct
vfio_pci_device'. The subsequent test patch will utilize this
to get the struct with very minimal initialization done.
Internally, let vfio_pci_device_init() also make use of this
function and later do the full initialization.

Symmetrically, add a free variant, vfio_pci_device_free(),
to be used in a similar fashion.

No functional change intended.
