[libvirt] [PATCH v2 0/4] util: Fixing libvirt errors on cavium/thunder-nicvf

ThunderX is Cavium SoC. This platform contain SRIOV NIC.
Unlike other commonly known network devices it does not have VF functionality
duplicated in its PF. PF is purely management device (on HW level).

This creates several problems with existing libvirt code as in many places
libvirt assumes that each VF netdev has PF netdev assigned. 

This patch series trying to address issues which can be easily fixed.
(mostly bug fixes found while working on full featured solution)

First patch in series is most important as it allows to unblock the netdev
detection and use <hostdev> on this platform.i <interface type="hostdev"
still does not work as it requires bigger changes both on netdev driver 
and in libvirt itself.
More details about those issues can be found at:

- error reporting taken out of virNetDevGetPhysicalFunction() and moved
  to calling function virNetDevGetVirtualFunctionInfo()
- curly braces removed from single line
- net-> model check removed as STREQ_NULLABLE() follows

  util: fixing wrong assumption that PF has to have netdev assigned
  util: Code simplification
  util: Fix for NULL dereference
  util: Fixing invalid error checking from virPCIGetNetname()
