Laine Stump 2c2525ab6a pci: initialize virtual_functions array pointer to avoid segfault 
This fixes https://bugzilla.redhat.com/show_bug.cgi?id=971325

The problem was that if virPCIGetVirtualFunctions was given the name
of a non-existent interface, it would return to its caller without
initializing the pointer to the array of virtual functions to NULL,
and the caller (virNetDevGetVirtualFunctions) would try to VIR_FREE()
the invalid pointer.

The final error message before the crash would be:

 virPCIGetVirtualFunctions:2088 :
  Failed to open dir '/sys/class/net/eth2/device':
  No such file or directory

In this patch I move the initialization in virPCIGetVirtualFunctions()
to the begining of the function, and also do an explicit
initialization in virNetDevGetVirtualFunctions, just in case someone
in the future adds code into that function prior to the call to
virPCIGetVirtualFunctions.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
