Xinyun Liu fb723efa48 dm: check pci_vdev before using 
acrn-dm runs to segmentation fault when failed to create VMs with
improper parameters.

If vdevs failed to be created, they are still be freed in deinit(),
and dereference the null pointers leads to segfault.

ACRN Device Model
#################

Introduction
============
The ACRN Device Model provides **device sharing** capabilities between the Service OS and Guest OSs. It is a component that is used in conjunction with the `ACRN Hypervisor`_ and this is installed within the Service OS. You can find out more about Project ACRN on the `Project ACRN documentation`_ website.
