vfio/pci: Move dummy_resources_list init in vfio_pci_probe()

Browse source

commit 16b8fe4caf upstream.

In case an error occurs in vfio_pci_enable() before the call to
vfio_pci_probe_mmaps(), vfio_pci_disable() will  try to iterate
on an uninitialized list and cause a kernel panic.

Lets move to the initialization to vfio_pci_probe() to fix the
issue.
