vfio/pci: Move dummy_resources_list init in vfio_pci_probe()
[ Upstream commit 16b8fe4caf499ae8e12d2ab1b1324497e36a7b83 ]
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.
